524 * Added more IM-like features by introducing new user modes
525 for setting various presence information. Added new modes:
526 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
527 specs and code. Protocol TODO #19. Affected files are
528 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
529 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
531 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
533 * Added STATS command to the protocol after all, to return
534 various statistical information about the network. It can
535 be used by clients to retrieve statistical information, and
536 servers may use it to to fetch cell and network wide
537 statistics from router. Updated the protocol specs and
538 implemented it to the server. Protocol TODO #16.
539 Affected files are lib/silccore/silccommand, silcd/command.[ch],
540 silcd/command_reply.[ch].
542 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
544 * The LIST command reply in client libary now adds new channel
545 entry if the returned channel doesn't exist yet in cache,
546 and returns the channel entry to the application in the
547 command_reply client operation. Affected file is
548 lib/silcclient/command_reply.c.
550 * Changed the channel message payload's MAC generation to
551 include the IV in the MAC as well. This way all relevant
552 parts of the channel message payload are authenticated also
553 with the channel message MAC (and not only by packet MAC).
554 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
555 Affected file is lib/silccore/silcchannel.c.
557 * Fixed the SKE to save the remote version, since the
558 silc_ske_parse_version mistakenly checked wrong version,
559 after it replaced the start payload. Affected files are
560 lib/silcske/silcske.[ch].
562 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
564 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
565 string utility functions. Added there also new functions
566 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
567 Affected files lib/silcutil/silcstrutil.[ch].
569 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
570 files are lib/silcutil/silcstrutil.[ch].
572 * Defined that the security property fields in SKE SHOULD be
573 UTF-8 encoded, defined that version string MUST be US-ASCII
574 encoded, defined that passphrases sent in connection
575 authentication protocol MUST be UTF-8 encoded. Implemented
576 these to the client and server. Defined also that other
577 passphrases sent in the protocol MUST be UTF-8 encoded.
578 Affected files are lib/silcske/silcske.c,
579 lib/silcclient/protocol.c, silcd/protocol.c,
580 silcd/serverconfig.c, and lib/silccore/silcauth.c.
582 * Changed the silc_client_close_connection interface to not
583 need the SilcSocketConnection which should not be visible
584 to application. Affected files are lib/silcclient/client.c
585 and lib/silcclient/silcclient.h.
587 * Rewrote the text for Private Message Key Payload in the
588 protocol specification. Protocol TODO #11.
590 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Upgraded the protocol version to 1.1, updated protocol specs
595 * Added the nickname as new argument to NICK_CHANGE notify and
596 added it to protocol specs and implemented it to client and
597 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
598 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
599 lib/silcclient/client_notify.c.
601 * Added the killer's client ID to the KILLED notify and added
602 it to protocol specs and implemented it to client and server.
603 Protocol TODO #13. Affected files are silcd/command.c,
604 silcd/packet_receive.c, packet_send.[ch],
605 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
606 The killer's client entry is now returned to application in
607 the `notify' client operation.
609 * Fixed the Max Argument fields that had too large value set
610 in the protocol specs. Protocol TODO #14.
612 * Added the LEAVE command reply to return the ID of parted
613 channel. Updated protocol specs and implemented it to the
614 client and server. Protocol TODO #15. Affected files are
615 silcd/command.c, lib/silcclient/command_reply.c. The channel
616 entry is now returned to application in the `command_reply'
619 * Rewrote the version SKE version checking in client libary
620 and in server to use the silc_parse_version_string. Affected
621 files are lib/silcclient/protocol.c, silcd/protocol.c.
623 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
624 commands that was missing it, and updated protocol specs and
625 the server implementation. Protocol TODO #10. The affected
626 file is silcd/command.c.
628 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
629 generic reply to a generic request (REQUEST flag), and
630 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
631 way. A draft-riikonen-silc-flags-payloads-00.txt is written
632 to define the payload for DATA flag. Added the flags to
633 the implementation. Protocol TODO #9. Affected file is
634 lib/silccore/silcchannel.h.
636 Changed the client library to return the message length
637 to application as well in the channel_message and private_message
638 client operations. Affected files are
639 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
640 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
641 and lib/silcclient/client_ops_example.c.
643 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
644 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
645 the channel. Updated protocol specs and impelemented this
646 to client and server. Protocol TODO #6. Affected files are
647 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
648 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
650 Added new options m and M to CMODE command in Irssi SILC
651 client to set these modes.
653 * Deprecated all administrative commands from SILC protocol
654 since they are highly implementation specific commands.
655 Updated protocol specs. Moved the old commands in
656 implementations to private range of command types. Affected
657 files are silcd/command.c, lib/silcclient/command.c and
658 lib/silcclient/command_reply.c. Protocol TODO #8.
660 * Fixed a bug in server where sending unknown command crashes
661 the server. Affected file silcd/command.c.
663 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
665 * Added SILC_PROTOCOLVERSION macro to check protocol version
666 of a socket connection. The affected file is
667 lib/silcutil/silcsockconn.h.
669 * Added better error logging in rekey protocol. Affected file
672 * Do not check public key types in SKE during rekey. Affected
673 file lib/silcske/payload.c.
675 * Fixed the rekey protocol with PFS, which was totally broken.
676 Affected file silcd/protocol.c.
678 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
680 * Some client implementations quit network by doing first LEAVE
681 and then immediately SIGNOFF (like Bombyx). We now do check
682 after a short time after LEAVE notify and check whether the
683 client is still valid after LEAVE, and if not we remove it from
684 cache. Affected file is lib/silcclient/client_notify.c.
686 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
688 * Merged version 1.1.4 of zlib. Even if it not currently in use,
689 it's good not to have security holes here.
691 * Fixed a negative refcount situtuation for the config context.
692 Affected file is silcd/serverconfig.c.
694 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
696 * ROBOdoc documented lib/silcutil/silcutil.h.
698 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Optimized even more the SilcPacketContext structure. Now
701 totally saved 16 bytes of memory per context after optimization.
702 Affected files are lib/silccore/silcpacket.[ch].
704 * Made strict checks for valid SILC IDs. Affected file is
705 lib/silccore/silcid.c.
707 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
709 * Changed the object argument for silc_cipher_register,
710 silc_hash_register, silc_hmac_register and silc_pkcs_register
711 to const. Affected files are lib/silccrypt/silccipher.[ch],
712 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
714 * Changed the silc_get_username and silc_get_real_name to
715 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
717 * Fixed the Irssi SILC Client to use the silc_get_username and
718 silc_get_real_name insted of glib routines since the glib
719 routines only corrupt stack. Fixes the Irssi SILC to work in
720 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
722 * Fixed the Irssi to not use g_get_home_dir since it crashes
723 or returns garbage on cygwin and corrupts stack. Added function
724 get_home_dir to Irssi routines. Affected files are
725 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
727 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Made some structure optimizations. SFTP memory FS MemFSEntry
730 entry structure. Optimized SilcTask structure. Optimized
731 SilcPacketContext structure.
733 Affected files lib/silcsftp/sftp_fs_memory.c,
734 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
736 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
738 * And yet again reverted back the config thing since Johnny
739 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
742 * Fixed memory leaks from config object. Affected files are
743 silcd/serverconfig.[ch].
745 * Added support for adding new connections to the server in rehash.
746 After rehash they take effect.
748 Added support for changing the maximum allowed connections in
749 rehash. The number can grow but going smaller is not supported.
751 Added function silc_server_num_sockets_by_remote to the
752 silcd/server_util.[ch].
754 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
756 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
758 * Added preliminary checking during config parsing for a valid
759 public/private key and removed further checks in the code.
760 Affected files are silcd/serverconfig.[ch], server.c.
762 * Moved functions silc_server_drop() and silc_server_daemonise()
763 from server.c to silcd.c since they are stricly related to
764 the application activity.
766 * Reverted a small part of the automatic ref/unref since
767 it caused a double unref in some situations. Affected
768 files are silcd/silcd.[ch], server.c, serverconfig.c.
770 * Added some .cvsignore files in the lib directory.
772 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Fixed silc_net_gethostbyaddr to correctly resolve by
775 address. Affected file lib/silcutil/silcnet.c.
777 * Fixed the notify relaying to client. The HMAC to be used
778 with relayed packets ws wrong and caused decryption failure
779 at the client end. Affected file is silcd/packet_receive.c.
781 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
783 * Created new branch silc_protocol_1_0_branch.
785 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
787 * Changed the silc_server_config_* routines to be SilcServer
788 independent. They are now officially application specific code
789 and not part of generic server implementation. Affected files
790 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
792 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
794 * Added automatic referencing of config context in the
795 silc_server_config_alloc, and automatic unreferencing in the
796 silc_server_config_destroy. Affected files are
797 silcd/serverconfig.[ch], silcd/silcd.c.
799 * Fixed the silc_log_quick handling in the logging routines.
800 It didn't log quickly when it was TRUE. Affected file is
801 lib/silcutil/silclog.c. Also the flush delay was set even
802 if it was 0 in config file. Affected file is
803 silcd/serverconfig.c.
805 * Added support for changing key pair of the server in rehash.
806 Affected file silcd/server.c.
808 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
810 * Fixed the TOPIC_SET notify to not cras. It changed the topic
811 too early, before getting the channel entry. Affected file
812 is silcd/packet_receive.c.
814 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
816 * Added functions silc_server_config_[ref/unref], these are used
817 to prevent that the config object is destroyed.
819 No longer directly affect global variables silc_log_quick and
820 silc_log_delay, they are first cached inside the config object
821 and then applied with silc_server_config_setlogfiles().
823 silc_server_config_set_defaults() is now internal to
824 serverconfig.c, there are no reasons to show this internal stuff
827 Affected files are silcd/serverconfig.[ch].
829 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
830 fprintf's to stderr, since some code may be executed again after
831 the server went into the background. Affected files are
834 * Added rehash support. Added function silc_server_rehash() that
835 will perform all the basic tasks of the rehashing procedure.
837 * Added command line option `-x, --hexdump'. This will enable the
838 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
839 The option `--hexdump' implies `--debug'.
841 * Fixed a bad bug in the logging APIs (silcutil library) where
842 the application would crash after calling silc_log_reset_all().
844 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
846 * Fixed the KICKED notify handling in client library to
847 correctly remove the channel and all entries from the
848 channel when I was kicked. This bug crashed the client.
850 Fixed yet another but in KICKED notify handling to remove
851 the kicked client correctly from the channel.
853 Affected file is lib/silcclient/client_notify.c.
855 * Fixed a minor bug in looking up correct client entry
856 in KICKED notify in server. Affected file is
857 silcd/packet_receive.c.
859 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
860 sources correctly to distribution. Fixes --with-gmp option.
862 * Removed the manual rehashing from ID Cache, and changed it
863 to use the SILC Hash Table's auto rehash feature. Affected
864 file is lib/silccore/silcidcache.c.
866 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
868 * Fixed a bug in the silc_client_nickname_format function that
869 handles the multiple same nickname formatting. Two clients
870 with same nickname caused problems after the first one left
871 and rejoined. It didn't format the nickname correctly.
872 Affected file is lib/silcclient/idlist.c.
874 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
876 * Don't change the topic if olod topic is same as new one.
877 Affected file is silcd/packet_receive.c.
879 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
881 * Added cross-reference support to the SILC Documentation
882 generator. All types across all HTML files are now cross-
883 referenced. Affected files util/robodoc/generator.c and
884 scripts/silcdoc/silcdoc.
886 * Added file lib/silcutil/silctypes.h to include all the
887 arithmetic type definitions and some macros. Removed
888 includes/bitmove.h and moved macros to silctypes.h.
890 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
892 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
894 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
896 * Added `type' argument to silc_id_payload_parse_id function which
897 now returns the type of the ID to the sent pointer. Affected
898 file is lib/silccore/silcid.[ch].
900 * Added check for CMODE_CHANGE notify type that mode change is
901 allowed by the sender. Affected file silcd/packet_receive.c.
903 * Added check for CUMODE_CHANGE notify type that mode change is
904 allowed by the sender. Affected file silcd/packet_receive.c.
905 Added the ID type as CUMODE_CHANGE notify type as argument
906 to the `notify' client operation. Affected files are
907 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
909 * Added function silc_client_add_server to the client library.
910 Added support for resolving also channel and server info when
911 received unknown entity in notify packet. Affected files are
912 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
914 * Added function silc_command_get_status to return the command
915 status from the command reply's argument payload. Affected files
916 are lib/silccore/silccommand.[ch].
918 * Added check for KICKED notify type that the kicking is
919 allowed by the client. Affected file silcd/packet_receive.c.
921 * Created function silc_get_input which can be used to get input
922 (echo on or off) from user on command line. Affected files are
923 lib/silcutil/silcutil.[ch].
925 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
927 * Optimized silc_server_packet_relay_to_channel function.
928 Added new function silc_channel_message_payload_encrypt which
929 can be called directly if channel message payload needs to
930 be encrypted and is already encoded (no need to call _encode
931 function). Packet relaying is now done by router without any
932 extra memory allocations. Affected files are
933 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
936 * Fixed the INVITE notify handling. It took wrong arguments
937 as invite list and invite delete. Affected file is
938 silcd/packet_receive.c.
940 * Added check for TOPIC_SET notify type that the topic change is
941 allowed by the client. Affected file silcd/packet_receive.c.
943 * Added check for INVITE notify type that inviting is allowed by
944 the client. Affected file silcd/packet_receive.c.
946 * Changed the silc_server_client_on_channel to return the
947 SilcChannelClientEntry as well. Moved the function
948 silc_server_check_cmode_rights to server_util.[ch].
949 Affected files are silcd/server_util.[ch], silcd/command.c.
951 * Added function silc_server_check_umode_rights to check whether
952 changing client's user mode is allowed. Added check for
953 UMODE_CHANGE notify type that the umode change is allowed
954 by the client. Affected files are silcd/server_util.[ch],
955 silcd/packet_receive.c and silcd/command.c.
957 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
959 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
960 ID length. It ignored that ID can be IPv6 based as well.
961 Affected file lib/silccore/silcpacket.h.
963 * Fixed the silc_id_id2str and silc_id_str2id to take the
964 IPv6 address offset's into consideration. Affecte file is
965 lib/silccore/silcid.c.
967 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
969 * Fixed the internal Unix scheduler functions to check for
970 NULL context they may receive. The affected file is
971 lib/silcutil/unix/silcunixschedule.c.
973 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
975 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
976 can specify different directory with --home command line
977 parameter. Affected files irssi/src/silc/core/client_ops.c,
980 * SILC-specific commands aren't now executed if the active server
981 isn't of SILC-type, so there won't be problems with having
982 IRC and SILC protocol support in same client. Affected files
983 irssi/src/silc/core/silc-channels.c, silc-servers.c,
986 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
988 * Improved the signal support in SILC Schedule. Added new
989 function silc_schedule_signal_call which is used by application
990 to mark a signal to be called. It is now safe to perform
991 any kind of tasks in signal callbacks since it is guaranteed
992 that the application specified signal callback is called
993 after the signal is over. Affected files are
994 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
996 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
998 * Added `name' field to SilcChannelPrivateKey to represent
999 application given name for the key. Moved also the context from
1000 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1001 Added the `name' argument also to the function
1002 silc_client_add_channel_private_key.
1004 Added function silc_client_current_channel_private_key to set the
1005 current channel private key in use.
1007 Added "change" command to KEY command which can be used to change
1008 the current channel private key. Bound the command also to
1009 alt+K (Alt+Shift+k).
1011 Also affected files lib/silcclient/client_channel.c,
1012 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1014 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1016 * Added silc_rng_get_byte_fast function in to the
1017 lib/silccrypt/silcrng.[ch].
1019 * Changed the interface of silc_packet_assemble and the
1020 silc_packet_send_prepare. If silc_packet_assmble is now
1021 called the application does not call silc_packet_send_prepare
1022 because the library will call it automatically. These
1023 interfaces now also return a reference to the outgoing buffer
1024 which includes the assembled packet, which the application can
1025 use to encrypt the packet.
1027 Affected files are lib/silccore/silcpacket.[ch],
1028 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1029 silcd/packet_send.c, server_backup.c and packet_receive.c.
1031 * Fixed a packet sending bug on very high load, where outgoing
1032 packet queue wasn't handled correctly and packets got corrupted.
1033 Affected files are lib/silcutil/*/silc*sockconn.c,
1034 lib/silcclient/client.c and silcd/server.c.
1036 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1038 * Added macro SILC_PACKET_DATALEN which can be used during
1039 packet assembling to check whether the data to be added to
1040 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1041 len is truncated until it fits it.
1043 Added checks for maximum length of channel message payload and
1044 private message payload also.
1046 Added checks for maximum packet length in server and in
1049 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1050 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1051 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1052 lib/silcclient/client_prvmsg.c.
1054 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1056 * Added silc_server_packet_queue_purge call to the
1057 silc_server_disconnect_remote to assure that all data in the
1058 queue before disconnecting is sent to the network. Affected
1059 file silcd/server.c.
1061 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1063 * Added the deleting of server's own ID cache entry to the
1064 silc_server_free function. Free also everything else that
1065 has been allocated in silc_server_init. The affected file
1068 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1070 * Added functions silc_parse_version_string, silc_version_to_num,
1071 and silc_ske_parse_version to parse SILC protocol style version
1072 strings. Affected files lib/silcutil/silcutil.[ch] and
1073 lib/silcske/silcske.[ch].
1075 * Added new configuration params: version_protocol, version_software
1076 and version_software_vendor to specify what version the remote
1077 host must at least be to be able to connect to server. The vendor
1078 string can be regex matched too. Added new function
1079 silc_server_connection_allowed to check maximum number of allowed
1080 connections, and allowed versions for incoming connections.
1081 Affected files are silcd/server.c, server_util.[ch] and
1084 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1086 * Added preliminary support for signals in scheduler. The
1087 signals we care about are now blocked always when the scheduler
1088 is locked. This way we can synchronise the use of signal with
1089 scheduler. It is guaranteed that when signal occurs the scheduler
1090 is not locked, and thus new tasks can be safely added to the
1093 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1094 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1095 Added new platform specific routines
1096 silc_schedule_internal_signals_[un]block and
1097 silc_schedule_internal_signal_[un]register.
1099 Added new functions to SILC Schedule API:
1100 silc_schedule_signal_[un]register. Each signal that application
1101 is going to use should be registered to the scheduler.
1103 Affected files are lib/silcutil/silcschedule.[ch],
1104 lib/silcutil/*/silc*schedule.c.
1106 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1108 * Check for unauthenticated client and server in the
1109 silc_server_new_client and silc_server_new_server functions.
1110 Affected file silcd/packet_receive.c.
1112 * Added function silc_string_is_ascii to check whether given
1113 string is 7-bit ASCII string. Affected files are
1114 lib/silcutil/silcutil.[ch].
1116 * Added function silc_id_is_valid_server_id into the
1117 silcd/serverid.c and added checking for valid Server ID's in
1118 silc_server_new_server. The Server ID must always be based
1119 on the server's public IP address.
1121 * Added logging of DISCONNECT packet message in the server.
1122 Affected file silcd/server.c.
1124 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1126 * Changed all library interfaces that use Global RNG to also
1127 accept SilcRng as argument. Affected files are
1128 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1129 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1130 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1131 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1132 lib/silccrypt/rsa.c.
1134 * Added function silc_pkcs_generate_key to the
1135 lib/silccrypt/silcpkcs.[ch] for applications so that they
1136 don't need to do pkcs->pkcs->init calls anymore.
1138 * Remove SilcSocketConnection from the SFTP API since it really
1139 wasn't needed there. The application has the information
1140 saved in its contexts anyway and the SFTP layer doesn't need
1141 know about it. Affected files lib/silcsft/silcsftp.h and
1142 lib/silcsftp/sftp_[server/client].c.
1144 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1145 The SilcSimContext is not SilcSim.
1147 * Fixed possible buffer overflows in silc_id_render in the
1148 lib/silcutil/silcutil.c.
1150 * On EPOC the global crypto module lists are not used at all
1151 in the crypto library. Added support for using the constant
1152 algorithm list on EPOC. Affected files are
1153 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1156 * Fixed the handling of third parameter of KICKED notify, since
1157 it was mistakenly updated to SILC Protocol 1.0 even though it
1158 is to be included in 1.1. Since it is not in 1.0 it is not
1159 mandatory, and this fix now handles it only if it is provided,
1160 and it is not error if it is not provided. Affected file
1161 lib/silcclient/client_notify.c.
1163 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1165 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1166 client. Affected file irssi/src/silc/core/client_ops.c.
1168 * Merged with Irssi 0.8.4 from irssi.org CVS.
1170 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1172 * Check for valid socket connection in client entries before
1173 sending any messages. Fixes a crash, but doesn't fix some
1174 other underlaying bug that is lurking there. Affected
1175 file silcd/packet_send.c.
1177 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1179 * $usermode, $cumode and $cumode_space expandos shouldn't do
1180 anything with non-SILC server records. Affected file
1181 irssi/src/silc/core/silc-expandos.c
1183 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Fixed the silc_net_check_[host/local]_by_sock to support
1186 IPv6 bound sockets as well. Now they can return IPv6 addresses
1187 as well. Affected file lib/silcutil/silcnet.c.
1189 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1190 Affected lib/silcutil/unix/silcunixnet.c.
1192 * Fixed ID rendering (at least on some platforms, not NetBSD)
1193 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1195 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1197 * Added silc_hash_public_key and silc_hash_public_key_compare
1198 functions to be used with SilcHashTable. They can be used to
1199 hash public keys and compare public keys in hash table. Affected
1200 file lib/silcutil/silcutil.[ch].
1202 * Added support for specifying multiple public keys for Client
1203 connection section in server configuration file. This makes it
1204 possible to accept multiple public keys from same host, or to
1205 make a section that accepts any incoming host, and have the
1206 accepted public keys listed in the section.
1208 Added functions silc_sever_[find/get]_public_key, added the
1209 support for this actually to all connection sections but only
1210 the Client section is currently allowed to specify multiple
1213 Affected files are silcd/server.c, server_internal.h,
1214 command.c, protocol.c, server_util.[ch], packet_receive.c.
1216 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1218 * Merged Irssi 0.8.2 from irssi.org CVS.
1220 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1222 * If silc_debug is TRUE, also output standard logging messages
1223 to stderr with the debug output.
1225 Made silc_log_reset_all() flushing all channels before returning.
1226 Also fixed some documentation typos.
1228 Affected files are lib/silcutil/silclog.[ch].
1230 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1232 * Fixed the server to check correctly the amount of connections
1233 from single host, by checking also the type of the connection.
1234 Fixed also the comparison of number of connections and number
1235 of allowed connections. Affected files are silcd/server.c,
1238 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1240 * Fixed the USERS command reply to save the user's mode on the
1241 channel as well. Fixed JOIN command reply to check whether a
1242 client is on channel already and not join it twice. Affected
1243 file lib/silcclient/command_reply.c.
1245 * Added new file silc-expandos.c into irssi/silc/core/ to return
1246 various stuff for various signal for the statusbar etc. updating.
1247 Now Irssi SILC client prints channel user modes etc. on the
1250 * The user mode (like server/router operator changes) is now shown
1251 on the Irssi SILC client's statusbar. The affected files are
1252 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1254 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1256 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1257 to SILC_SCHEDULE_[UN]LOCK macros.
1259 * Added more error printing to logs in server code. Affected
1260 files silcd/server.c and silcd/protocol.c.
1262 * Fixed -S option parsing in Irssi SILC Client. Affected file
1263 irssi/src/silc/core/silc-core.c.
1265 * Added silc_buffer_alloc_size function. Affected file is
1266 lib/silcutil/silcbuffer.h.
1268 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1270 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1271 constants. Affected files in
1272 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1275 * Changed the internal SFTP Memory FS table to const. Affected
1276 file lib/silcsftp/sftp_fs_memory.c.

1280 * Fixed the buffer formatting and unformatting routines to
1281 check the size of 64 bits types with sizeof(). Affected
1282 file is lib/silcutil/silcbuffmt.c.
1284 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1288 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1290 * Changed all integer type names:
1291 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1292 to avoid collisions with other libraries using same type names
1295 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1297 * Added `prefer_ipv6' argument to the functions
1298 silc_net_gethostbyname[_async]. If it is TRUE it will return
1299 IPv6 address over IPv4. If FALSE IPv4 address is returned
1300 even if IPv6 address was found. Affected files
1301 lib/silcutil/silcnet.[ch].
1303 * Added support silc_net_create_connection[_async] to fallback
1304 to IPv4 address if IPv6 address could not be used (like if
1305 it doesn't work on a specific system). Affected file in
1306 lib/silcutil/unix/silcunixnet.c.
1308 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1310 * Added silc_schedule_reinit function to do the enlarging
1311 of the max tasks handling capabilities of the scheduler.
1312 Affected files lib/silcutil/silcschedule.[ch].
1314 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1316 * Added automatic extern "C" { ... } for C++ compilers so the
1317 application does not need to define them. Affected file
1318 includes/silcincludes.h.
1320 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1321 old name went against naming convention. Applications now
1322 include "silcclient.h" instead of "clientlibincludes.h".
1323 Removed includes/clientlibincludes.h, it is redundant now.
1325 * Renamed includes/version.h to silcversion.h.
1327 * Added really preliminary support for OS/2 into the util
1328 library. Only thread & mutex API is implemented, others
1329 are still to be implemented. Created the lib/silcutil/os2/
1330 directory. Created also file includes/silcos2.h.
1332 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1335 Created lib/silcutil/beos/, and implemented all the needed
1336 functions to support SILC on BeOS. Created also file
1337 includes/silcbeos.h.
1339 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1341 * Added proper initializations to silc's irssi code, so it's
1342 now possible to load it as module. Affected files
1343 irssi/src/silc/core/silc-core.c,
1344 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1363 * Added `user_count' to the SilcChannelEntry which now tells the
1364 number of users on the channel. The user count is now saved
1365 in normal server of global channels as well. Affected files
1366 silcd/server.c, idlist.h, packet_receive.c and command.c.
1368 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1369 include file utility functions.
1371 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1372 instead of calling directly OS routines.
1374 * Fixed NICK change printing in Irssi SILC Client. Fixed
1375 KICKED notify printing in Irssi SILC Client. Affected file
1376 irssi/src/silc/core/client_ops.c.
1378 * Fixed a NICK change bug in client library, to not recreate the
1379 client_entry->channels hash table everytime nick is changed.
1380 Affected file lib/silcclient/client.c.
1382 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1385 the SKE interface a bit.
1387 * Fixed padding problem in PKCS#1. The padding was not actually
1388 random since the random number generator was used incorrectly.
1389 This security bug affects only when encrypting with PKCS#1, and
1390 it is not currently used at all in SILC. SILC only use signing
1391 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1393 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1397 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1399 * Send the auto-nicking NICK command in client library with
1400 little timeout after connecting. The affected file is
1401 lib/silcclient/client.c.
1403 * Added following new config file settings:
1404 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1405 key_exchange_timeout, conn_auth_timeout, connections_max,
1408 Implemented all the new config settings handling in the server.
1410 Optimized the use of SKE Mutual flag usage. Use it only
1411 if connection authentication protocol is not based in public
1414 Renamed all SilcServerConfigSection* to SilcServerConfig*
1415 to have a bit shorter names.
1417 Affected files silcd/serverconfig.[ch], server.[ch], and
1420 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1446 Affected files are silcd/serverconfig.[ch].
1448 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1450 * Fixed command line parameter handling. All SILC initialization
1451 is now done in silc_core_init() which also fixes autoconnecting
1454 Affected files irssi/src/silc/core/silc-core.c,
1455 irssi/src/fe-text/silc.c.
1457 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1459 * Added new configuration options and blocks:
1460 keepalive_secs, reconnect_count, reconnect_interval,
1461 reconnect_interval_max, reconnect_keep_trying and
1462 require_reverser_lookup. Added ConnectionParam block, and
1463 implemented the connection parameters when connecting as
1464 initiator and when accepting connections as responder.
1466 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1467 whether given configuration value has been given already.
1469 Affected files silcd/serverconfig.[c], server.[c].
1471 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1472 algorithm parts and created new file silcalgs.conf, that
1473 is now included from the example_silcd.conf.in.
1475 * Optimized the silc_server_connect_to_router_second to take
1476 the connection configuration object from the SilcServerConnection
1477 object instead of finding it during the connecting phase.
1478 Added the configuration object to SilcServerConnection struct.
1479 Affected files silcd/server_internal.h, server.c.
1481 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1483 * Add the client on channel after it was resolved at the
1484 channel message receiving, and it was not already on the
1485 channel. Affected file lib/silcclient/client_channel.c.
1487 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1489 * Fixed the public key authentication to allocate always the
1490 destination signature buffer instead of using static buffer.
1491 Affected file silcd/protocol.c.
1493 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1495 * Unified the serverconfig.[ch]'s helper function interface.
1496 Affected file silcd/serverconfig.[ch].
1498 * Removed doc/example_silc.conf.in since it is redundant.
1499 The make install will now install irssi/silc.conf file.
1501 * Added new Passphrase and Publickey authentication methods to
1502 config file, allowing both public key and passphrase based
1503 authentication to be set at the same time.
1505 Added `prefer_passphrase_auth' setting in config file which
1506 can be used to set to prefer passwd auth if both passwd and
1507 public key is set. If not set, public key is preferred.
1508 This has effect only when being initiator (responder will try
1511 Added support for authentication with passphrase and public key
1512 at the same time. The passphrase is tried first always since
1513 it is faster to check.
1515 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1517 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1519 * Merged the new SILC Config library, with the server parsing
1520 support. Read the header file silcconfig.h or the toolkit

1546 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1547 as header filenames.
1549 * Removed lib/silcclient/README and created HTML file
1550 lib/silcclient/silcclient_using.html, which is now included
1551 as part of Toolkit documentation.
1553 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1555 * Fixed CUMODE_CHANGE notify handling to change the mode of
1556 correct client. Affected file lib/silcclient/client_notify.c.
1558 * Make silc_rng_alloc fail if it cannot allocate the sha1
1559 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1561 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1563 * Fixed the file transfer's key agreement payload to include
1564 zero port also if the hostname is NULL because it could not
1567 Call file transfer monitor callback now also if error occurs
1568 during key agreement protocol.
1570 Changed the silc_client_file_send interface to return the
1571 SilcClientFileError instead of session id. The session ID
1572 is returned into pointer provided as argument.
1574 Check that the file exists locally before sending the
1575 file transfer request at all.
1577 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1579 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1580 error than can occur while key agreement protocol. Affected
1581 file lib/silcclient/silcapi.h.
1583 * Fixed the event_mode CMODE handler to not crash when mode
1584 is changed and +k mode is set in the channel. Affected file
1585 irssi/src/silc/core/silc-channels.c.
1587 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1588 SILC_LOG_WARNING to give out Warning and not Error. Affected
1589 file lib/silcutil/silclog.c.
1591 * Fixed the channel message payload decryption in the function
1592 silc_channel_message_payload_decrypt to not modify the original
1593 buffer before it is verified that the message decrypted
1594 correctly. Otherwise, next time it is called with correct
1595 channel key it won't encrypt since the payload is corrupted.
1596 Affected file lib/silccore/silcchannel.c.
1598 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1600 * Do not constantly resize the window. A fix patch by cras.
1601 Affected file irssi/src/fe-text/screen.c.
1603 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1605 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1606 Affected file lib/silcutil/silcnet.c.
1608 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1610 * Fixed a bug in hash table internal routine for traversing
1611 the table with foreach callback. The current entry may
1612 become invalid in the callback but it was referenced after
1613 the callback returned.
1615 Do not allow auto rehashing of hash table during the
1616 silc_hash_table_foreach operation, for same reasons as it is
1617 not allowed for SilcHashTableList. Affected files are
1618 lib/silcutil/silchashtable.[ch].
1620 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1622 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1623 Win32 DLL. extern's in header files are now declared with
1626 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1628 * Fixed private message handling. It used some old code that
1629 caused the client to crash. Affecte file is
1630 lib/silcclient/client_prvmsg.c.
1632 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1634 * Added function silc_client_add_channel,
1635 silc_client_replace_channel_id, and removed functions
1636 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1637 from client library.
1639 * Added cross reference of the joined channels to the
1640 SilcClientEntry, and changed the SilcChannelEntry's
1641 users list to SilcHashTable. The affected files are
1642 lib/silcclient/idlist.[ch].
1644 * Fixed a bug in hash table tarversing. While the hash table
1645 is traversed with SilcHashTableList the table must not be
1646 rehashed. It is now guaranteed that auto rehashable tables
1647 are not rehashed while tarversing the list. Also defined that
1648 silc_hash_table_rehash must not be called while tarversing
1649 the table. Added function silc_hash_table_list_reset that must
1650 be called after the tarversing is over. The affected files are
1651 lib/silcutil/silchashtable.[ch].
1653 * Changed all hash table traversing to call the new
1654 silc_hash_table_list_reset in server and in client library.
1656 * Added function silc_client_on_channel to return the
1657 SilcChannelUser entry if the specified client entry is joined
1658 on the specified channel. This is exported to application as
1659 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1661 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1663 * Fixed founder regaining problem with JOIN command on normal
1664 server. The notify for mode change must be sent always and
1665 not only if !cmd->pending. Affected file silcd/command.c.
1667 * Fixed the WHOWAS command's reply sending to support the
1668 lists correctly. Affected file silcd/command.c.
1670 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1672 * When sending JOIN command to router for processing the
1673 sender's old command identifier was not saved back to the
1674 sender's command context, fixed now. The affected file is
1677 * Create the key in JOIN command of the router did not return
1678 the channel key, added check for this. Affected file is
1681 * Fixed a channel ID update bug in JOIN command reply. Do
1682 not directly upgrade the ID but call the function
1683 silc_idlist_replace_channel_id if the ID was changed.
1684 Affected file silcd/command_reply.c.
1686 * Fixed memory leaks from command calling if it would fail.
1687 Affected file silcd/command.c.
1689 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1691 * Applied patches from cras:
1693 Memory leak fixes around libaries, irssi window resize fix,
1694 new silclist.h and silcdlist.h, all extern inline changed to
1697 * Removed dotconf from lib/dotconf, not needed anymore.
1699 * Removed TRQ from lib/trq, not needed anymore.
1701 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1702 with server connections. Later this will be configurable
1703 in config file after new config file is done. Affected file
1706 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Fixed a crash in server related to channel announcements.
1709 Affected file silcd/server.c.
1711 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed memory leaks in silc_server_create_new_channel*
1714 functions. Affected file silcd/server.c.
1716 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1717 which ID was changed. This way the router will send the
1718 user list for the channel again, and server won't be in
1719 desync in some rare circumstances. Affected file is
1720 silcd/packet_receive.c.
1722 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1724 * Check for NULL socket pointer in the function
1725 silc_server_packet_send_to_channel_real. Affected file
1726 silcd/packet_send.c.
1728 * Fixed the BAN notify handling to correctly remove ban
1729 list. Affected file silcd/packet_receive.c.
1731 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1733 * Fixed some header addition to Toolkit distribution in
1734 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1736 * Added lib/silcclient/client_ops_example.h as an template
1737 file for application programmers to quickly start using
1738 the SilcClientOperation functions in their application.
1739 Updated the lib/silcclient/README as well to tell about this
1740 nice file made available.
1742 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1744 * Call silc_server_remove_from_channels when removing client
1745 entry when NO_SUCH_CLIENT_ID was received. Affected file
1746 is silcd/command_reply.c.
1748 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1750 * Added server & router operator statistics updating. Affected
1751 file silcd/packet_receive.c and silcd/command.c.
1753 * Fixed the SERVER_SIGNOFF notify handling on normal server
1754 not to save the history information for clients. Same was
1755 fixed earlier in remove_clients_by_server function, but not
1756 here. Affected file silcd/packet_receive.c.
1758 * Raised the default connection-retry count from 4 to 7 in
1759 server. Affected file silcd/server.h.
1761 * Cancel any possible reconnect timeouts when we start the
1762 key exchange. Affected file silcd/server.c.
1764 * Do not reconnect on connection failure when SCONNECT was
1765 given. Affected files silcd/server.[ch].
1767 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1769 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1771 * Fixed the NICK command to always give the unformatted
1772 nickname to the one giving the NICK command. If unformatted
1773 nickname is cached already it will be formatted and the
1774 local entry will always get the unformatted nickname.
1775 Affected file lib/silcclient/idlist.c.
1777 * Fixed some double frees from client library commands.
1778 Affected file is lib/silcclient/command.c.
1780 * Fixed CUMODE command in server to assure that no one can
1781 change founder's mode than the founder itself, there was a
1782 little bug. Affected file silcd/command.c.
1784 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1786 * Removed the SilcClientCommandDestructor from the client
1787 libary, it is not needed anymore. Affected files are
1788 lib/silcclient/silcapi.h, command[_reply].[ch],
1789 client_notify, idlist.c.
1791 * Fixed GETKEY command to first resolve client, and then
1792 resolve the server only if the client was not found, instead
1793 of resolving both at the same time. Affected file is
1794 lib/silcclient/command.c.
1796 * Added silc_client_start_key_exchange_cb and lookup the
1797 remote hostname and IP address before starting the key
1798 exchange with server. The affected file is
1799 lib/silcclient/client.c.
1801 * The server's public key is now saved using the IP address
1802 of the server and not the servername for the filename.
1803 The hostname public key filename is checked as an fall back
1804 method if the IP address based filename is not found.
1806 Fixed the GETKEY command to save the fetched server key
1807 in correct filename.
1809 Print the remote server's hostname now when new key is
1810 received during connection process. Affected file is
1811 irssi/src/silc/core/client_ops.c.
1813 * Return always our own public key to the client if it asks
1814 for it with GETKEY command. Affected file silcd/command.c.
1816 * Removed the use_auto_addr variable from default config
1817 file since it was in wrong section. Affected file is
1820 * Fixed TOPIC_CHANGE notification to not route it when it
1821 was sent using silc_server_send_notify_to_channel function.
1822 Affected file silcd/command.c.
1824 * Fixed silc_server_send_notify_kicked to send the kicker's
1825 Client ID also, it was missing. Affected files are
1826 silcd/command.c, silcd/packet_send.[ch].
1828 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1830 * Do not save client history information in SERVER_SIGNOFF.
1831 Fixes the bug in normal server that it does not detect
1832 the client becoming valid after the server becomes back
1833 online. Affected file silcd/server_util.c.
1835 * Added `sock_error' field into the SilcSocketConnection
1836 context. When error occurs during socket operation (read
1837 or write) the error is saved. Added also new function
1838 silc_socket_get_error to return human readable socket error
1839 message. Affected files are lib/silcutil/silcsockconn.[ch],
1840 lib/silcutil/unix/silcunixsockconn.c, and
1841 lib/silcutil/win32/silcwin32sockconn.c.
1843 * The server now prints the socket error message in the
1844 signoff for client. Affected file silcd/server.c.
1846 * Fixed the `created' channel information sending from router
1847 to server in JOIN command. Checks now whether the channel
1848 really was created or not and set it according that.
1850 Fixed the JOIN command to use the client entry's current
1851 ID during the joining procedure instead of the one it sent
1852 in the command (it is checked though), since it can change
1853 between the packet processing and command processing, and
1854 would just case unnecessary pain in the client end. Affected
1855 file silcd/command.c.
1857 * Fixed a channel key payload sending to use correct channel
1858 ID when the server was forced to change the channel's ID by
1859 router. Router sent the key payload with the old Channel ID.
1860 Affected file silcd/packet_receive.c.
1862 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1864 * Call silc_server_save_channel_key only if the key payload
1865 was provided in the JOIN command's command reply. Affected
1866 file silcd/command_reply.c.
1868 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1870 * Fixed silc_mp_sizeinbase to return the value correctly with
1871 MPI. Affected file lib/silcmath/mp_mpi.c.
1873 * Fixed the stop_server signal to correctly stop the scheduler
1874 and gracefully stop the server when SIGTERM or SIGINT signals
1875 are received. Affected file silcd/silcd.c.
1877 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1879 * Simple handling of TERM and HUP signals. Also added some log
1880 flushing call around. Affected file is
1883 * Fixed small bugs in silclog.c. Now buffering output will take
1884 effect after 10 seconds since startup: This will ensure that
1885 no important startup messages are lost. Also output redirection
1886 will preserve original format ([Date] [Type] message).
1887 Affected file is lib/silcutil/silclog.c.
1889 * Added two options to the config file, in the logging section:
1890 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1891 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1893 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1895 * Do not print the warning about log files not being initialized
1896 more than once to avoid excess logging. Affected file is
1897 lib/silcutil/silclog.c.
1899 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1900 the SIM copying in make install in Makefile.am.pre.
1902 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1904 * Rewritten silclog APIs. Globally interesting changes follows:
1905 silc_log_set_files() changed to silc_log_set_file().
1906 silc_log_set_callbacks() changed to silc_log_set_callback().
1907 ROBOdoc documented silclog header file.
1908 SilcLogCb now returns bool to wether inihibit the default
1909 handler or not (to keep the old behaviour return always TRUE).
1910 The new APIs should also fix the problem of the
1911 silcd_error.log file that was written in the current directory.
1914 Log files streams will remain opened after silc_log_set_file()
1915 call, means less CPU usage notably on high traffic servers.
1916 File streams are now full buffered, and flushed to the disk
1917 every 5 minutes, lesses HD activity and CPU usage.
1918 Messages can be redirected, allowing admins to configure
1919 one single logfile for all server messages.
1920 the silc_log_quick global variable to activate fast-logging.
1921 Affected files lib/silcutil/silclog.[ch]
1923 * Changed some code to conform new silclog APIs. Affected
1924 files are doc/example_silcd.conf.in, silcd/server.c
1925 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1928 * Fixed a memory leak that could occur in some situations.
1929 Affected file silcd/serverconfig.c.
1931 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1933 * Added the silc_client_del_client to remove the client from
1934 all channels as well. Affected file lib/silcclient/idlist.c.
1936 * Fixed the client library to correctly remove the client
1937 from all channels when the client entry is being destroyed.
1938 Affected file lib/silcclient/client_notify.c, command.c.
1940 * Added auto-nicking support to the client library. If the
1941 applicatio now sets client->nickname it will be sent to the
1942 server after connecting by the library. This way for example
1943 SILCNICK (or IRCNICK) environment variables will have effect
1944 and always change the nickname automatically to whatever
1945 it is wanted. Affected file lib/silcclient/client.[ch].
1947 * Renamed silc_server_command_bad_chars to the
1948 silc_server_name_bad_chars and moved it to the
1949 silcd/server_util.[ch]. Added also new function
1950 silc_server_name_modify_bad to return nickname that
1951 includes bad characters as new nickname without those
1952 bad characters. This check and modify is now used in
1953 silc_server_new_client when the username is initially set
1954 as nickname, so it must be checked to be valid nickname.
1955 Affected file silcd/packet_receive.c.
1957 * The nickname length is now taken from the packet for real
1958 and not trusted to strlen() since it clearly can return
1959 wrong length for nickname including bad characters. This
1960 also applies to channel names. Affected file silcd/command.c.
1962 * Removed the lib/silcsilm/modules directory. Modules are now
1963 compiled into the lib/silcsim. Fixed the copying of the
1964 modules to follow symbolic links in Makefile.am.pre.
1966 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1968 * Fixed silc_string_regexify list creation. Fixes bugs with
1969 BAN and INVITE commands in server. The affected file is
1970 lib/silcutil/unix/silcunixutil.c.
1972 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Removed the command destructor entirely from the server's
1975 command and command reply routines. It is not needed, and
1976 its usage was buggy and caused crashes. Affected files are
1977 silcd/command[_reply].[ch].
1979 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Cancel protocol and NULL sock->protocol if timeout
1982 occurred during protocol. Affected file silcd/server.c.
1984 * Cancel protocol timeouts always before calling the final
1985 callback, to assure that after final callback is called
1986 no other state will be called for the protocol anymore.
1987 Affected file silcd/protocol.c.
1989 * Print error log if incoming connection configuration could
1990 not be found. Affected file silcd/server.c.
1992 * Fixed JOIN command to correctly save the founder mode
1993 to the client on normal SILC server, when the channel
1994 was created by the router. Affected file silcd/command.c.
1996 * Fixed LIST command (hopefully) to send correct reply
1997 packets. Affected file silcd/command.c.
1999 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2001 * The silc_packet_receive_process now returns FALSE if the
2002 read data was invalid packet, and TRUE if it was ok.
2004 The server now checks that if unauthenticated connection
2005 sends data and its processing fails the server will close
2006 the connection since it could be a malicious flooder.
2008 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2010 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Make sure the warning about error opening a log file is
2013 printed only once and not everytime it fails (produces
2014 too much useless log). Affected file lib/silcutil/silclog.c.
2016 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2018 * Made the silc_server_daemonise() function more readable.
2019 Affected file silcd/server.c.
2021 * Pid file is now optional, the user may comment it out from
2022 the config file. Removed define SILC_SERVER_PID_FILE, we
2023 don't need a default any longer. Affected file
2024 configure.in.pre, lib/Makefile.am.pre.
2026 * Make some use of the pid file. The server now dies at startup
2027 if it detects a valid pid file on his path. The server would
2028 die anyway in this circumstance, because of the bind() failure.
2029 Affected file silcd/silcd.c.
2031 * No longer compiling lib/dotconf.
2033 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Fixed JOIN command parsing not to crash. Affected file
2036 lib/silcclient/command.c.
2038 * Fied the NICK_CHANGE notify to add the new client entry
2039 even it is resolved. This removes an <[unknown]> nick
2040 thingy bug in the client. Affected file is
2041 lib/silcclient/client_notify.c.
2043 * Do not try to allocate 0 bytes (efence does not like it)
2044 in lib/silccore/silccomand.c when encoding payload.
2046 * Do not take IRCNICK as nickname in Irssi SILC client since
2047 it is not possible to set nickname before hand connecting
2048 the server (TODO has an entry about adding auto-nicking
2051 * Changed the silc_server_command_pending to check whether
2052 there already exists an pending entry with the specified
2053 command, command identifier and pending callback. This is
2054 to fix IDENTIFY and WHOIS related crashes that may register
2055 multiple pending commands with same identifier. Affected
2056 file silcd/command.c.
2058 * Fixed the server to reconnect to the router even if it
2059 was already reconnecting and EOF was received. This to
2060 fix a possibility that the server wouldn't ever try to
2061 auto-reconnect to the router. Affected file silcd/server.c.
2063 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Fixed the server's password authentication to use the
2066 length of the locally saved password, and not the one
2067 sent in the packet. Affected file silcd/protocol.c.
2069 * Fixed same password authentication problem in the
2070 Authentication Payload handling routines in
2071 lib/silccore/silcauth.c.
2073 * Yet another password authentication problem fixed with
2074 channel password handling in silcd/command.c.
2076 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * If first character of string in silc_parse_userfqdn is '@'
2079 then do not parse it. Affected file is
2080 lib/silcutil/silcutil.c.
2082 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Fixed minor bug in IDENTIFY command reply sending, which
2085 caused various weird problems during JOIN when it was
2086 resolving names for users. Affected file silcd/command.c.
2088 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Fixed the IDENTIFY command reply sending to chech better valid
2091 clients. It was possible to send incomplete list of replies.
2092 Affected file silcd/command.c.
2094 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Added silc_client_command[s]_[un]register functions now to
2097 dynamically register the commands in client library. Removed
2098 the static table of commands. This allows the client library
2099 to call commands without causing the application to know about
2100 what commands library has called.
2102 Removed the INFO command reply kludge to detect when the command
2103 was called by library. Now library use its own command reply
2104 function for INFO command.
2106 Added function silc_client_command_call to call a command.
2107 Application can use it to call command, not access the structure
2110 Now all commands that are sent by the client library (not
2111 explicitly sent by application) use own command reply functions.
2113 Affected files around lib/silcclient/ and in
2114 irssi/src/silc/core/.
2116 * Fixed the WHOIS command reply sending to chech better valid
2117 clients. It was possible to send incomplete list of replies.
2119 Fixed the WHOIS and IDENTIFY to send the request to router
2120 if normal server did not do it and did not find any results.
2122 Affected file silcd/command.c.
2124 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2126 * Moved the internal data from SilcClient context into its
2127 own file, not accesible to application. Affected files
2128 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2129 and other files in client library.
2131 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Added doc/examples installation target in Makefile.am.pre.
2136 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2139 commands the found client entry will be removed from the
2140 cache, after notifying application about the error. Affected
2141 file lib/silcclient/command_reply.c.
2143 * Changed the /MSG to check for exact nickname user gave, and
2144 not let `nick' match `nick@host' if it is only one found. Now,
2145 user must type the exact nickname (like nick@host2) even if
2146 there are no more than one same nicks found. This is to avoid
2147 a possibility of sending nickname to wrong nickname since
2148 `nick' could match `nick@host'. Affected file is
2149 irssi/src/core/silc-servers.c.
2151 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Do not print "you are now server operator" or similar when
2154 giving /away command. Affected files are
2155 irssi/src/silc/core/client_ops.c, silc-servers.h.
2157 * Made the silc_server_command_pending_error_check to send
2158 the same command reply payload it received back to the
2159 original sender of the command. This way all arguments
2160 that was received by the server will be received by the
2161 client too. Affected file silcd/command.c.
2163 * Added the silc_idcache_add to return the created cache entry
2164 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2166 * Add global clients to expire if they are not on any channel.
2167 This is because normal server will never know if they signoff
2168 if they are not on any channel. The cache expiry will take
2169 case of these entries. This is done by normal servers only.
2170 The affected files are silcd/command_reply.c,
2171 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2173 * If server receives invalid ID notification for WHOIS or
2174 IDENTIFY and the ID exists in the lists, it is removed.
2175 Affected file silcd/command_reply.c.
2177 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2178 in client then client entry that it matches is searched and
2179 the nickname is printed on the screen for user. Affected
2180 file irssi/src/silc/core/client_ops.c.
2182 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Use cache entry expire time in the LIST command reply to
2185 purge old entries from the cache after the LIST command
2186 reply has been received. This way we don't have non-existent
2187 entries in the cache for too long. Affected file is
2188 silcd/command_reply.c.
2190 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * If we are normal server, and we've not resolved client info
2193 in WHOIS or IDENTIFY from router, and it is global client,
2194 we'll check whether it is on some channel. If it is not
2195 then we cannot be sure about its validity and will resolve it
2196 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2197 file silcd/command.c.
2199 * Search channel by name (if possible) rather than by ID
2200 in IDENTIFY command's command reply. Affected file is
2201 silcd/command_reply.c.
2203 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2205 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2206 Updated specs and implemented it. Affected file silcd/command.c,
2207 silcd/packet_send.c and silcd/packet_receive.c.
2209 * Implemented the <founder auth> payload handling in the JOIN
2210 command. If provided all conditions for channel joining
2211 except requirement to provide correct passphrase can be
2212 overrided by the channel founder. Updated the protocol specs.
2213 Affected file silcd/command.c.
2215 Added support for founder auth in JOIN command in client
2216 library. Fixed the parsing of the JOIN command now to support
2217 all options as they should be. The affected file is
2218 lib/silcclient/command.c.
2220 * Optimized the WHOIS and IDENTIFY commands to send the request
2221 to router only if it includes nicknames or other names. If
2222 they include only IDs then check the local cache first before
2223 routing. Affected file is silcd/command.c.
2225 * Added channels topic announcements. Affected file is
2226 silcd/packet_receive.c and silcd/server.c.
2228 * Fixed the silc_server_send_notify_topic_set to really destine
2229 the packet to channel. Affected file silcd/packet_send.c.
2231 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2232 library. Affected file lib/silcclient/client_notify.c.
2234 * Added UMODE announcements. Affected file silcd/server.c.
2236 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * Memory leak fixes in:
2240 lib/silcutil/silcsockconn.c
2241 lib/silcske/silcske.c
2242 lib/silcske/groups.c
2244 lib/silccrypt/silcpkcs.c
2245 lib/silccore/silccommand.c
2246 lib/silccore/silcidcache.c
2251 * ROBOdoc documented the lib/silcske/groups.h file and a
2252 bit changed the interface for better.
2254 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2256 * Update the client entry context in the ID cache after
2257 nick change. Affected file lib/silcclient/command.c.
2258 Fixes the CUMODE command when regaining founder privileges,
2259 and a little WHOIS problem.
2261 * Fixed silc_net_gethostbyname to correctly call the
2262 inet_ntop. Affected file lib/silcutil/silcnet.c.
2264 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2266 * Added IPv6 support checking to the configure.in.pre, added
2267 also --enable-ipv6 option to override the check. Affected
2268 file configure.in.pre.
2270 * The silc_thread_create now calls the start function
2271 directly if threads support is not compiled in. Removes
2272 ugly #ifdef's from generic code. Affected files are
2273 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2275 * Added silc_net_gethostby[name/addr]_async to asynchronously
2276 resolve. Affected files are lib/silcutil/silcnet.[ch].
2278 * Added support for rendering IPv6 based server, client and
2279 channel IDs. Affected file lib/silcutil/silcutil.c.
2281 * Added support for creating IPv6 based server IDs. Affected
2282 file is silcd/serverid.c.
2284 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2286 * Added silc_net_gethostby[addr/name] into the
2287 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2288 routines. Added silc_net_is_ip[4/6]. Affected file is
2289 lib/silcutil/unix/silcunixnet.c. All routines that take
2290 address as argument now supports both IPv4 and IPv6 addresses.
2292 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2294 * Fixed LIST command reply sending in server. Affected file
2297 * Server now sends the kicker's client ID in the KICK notify
2298 to the kicked client. Affected file silcd/command.c.
2300 * The client library now parses the kickers client ID and
2301 UI displays it. Affected files lib/silcclient/client_notify.c
2302 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2304 * Made all payload parsing function prototypes consistent.
2305 They all take now const unsigned char * and uint32 pair as
2306 the payload data instead of SilcBuffer. Changes all around
2307 the source tree. Other unsigned char* -> const unsigned char*
2308 changes around the tree as well.
2310 * Optimized SFTP client and server packet sending not to
2311 allocate new buffer for each packet but to recycle the
2312 first allocated buffer. Affected files are
2313 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2315 * Optimized the SFTP client to use SilcList instead of
2316 SilcDList for requests, because it is faster. Affected file
2317 is lib/silcsftp/sftp_client.c.
2319 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2320 into lib/silccore/silcid.[ch].
2322 Renamed silcpayload.[ch] into silcargument.[ch].
2324 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * If client entry is deleted with active key agreement
2327 session, abort the session.
2329 The silc_client_abort_key_agreement now calls the completion
2330 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2332 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2335 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2337 * Don't use __restrict in older GCC's. Affected file is
2338 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2340 * silc_net_localhost now attempts to reverse lookup the
2341 IP/hostname. Affected file lib/silcutil/silcnet.c.
2343 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2344 command. It can be used to gain founder privileges at
2345 the same time when joining the channel.
2347 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2348 kicker's client ID as well. Updated protocol specs.
2350 Defined that the server must send SILC_COMMAND_IDENTIFY
2351 command reply with error status to client who sent
2352 private message with invalid client ID.
2354 Updated the protocol specification.
2356 * Added silc_server_send_command_reply to send any
2357 command reply. Affected file silcd/packet_send.[ch].
2359 * Added silc_id_payload_encode_data to encode ID payload
2360 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2362 * The server now send IDENTIFY command reply with error
2363 status if client ID in private message is invalid. Affected
2364 file silcd/packet_receive.c.
2366 * Save the server key file with server's IP address in
2367 the filename instead of hostname. The affected file is
2368 irssi/src/silc/core/client_ops.c.
2370 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2372 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2375 * Added libtool support for compiling shared objects in
2376 lib/silcsim. Affected file configure.in.pre and
2377 lib/silcsim/Makefile.am. Original patch by cras.
2379 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Pid file configuration, and server's config file fixes
2382 patch by toma. Updated CREDITS file.
2384 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Fixed silc_client_channel_message to not try to decrypt
2387 the message twice if it resolved the destination client
2388 information. This could cause of dropping one channel
2389 message. Affected file lib/silcclient/client_channel.c.
2391 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2394 lib/silcclient/client.c. This function is used when the SILC
2395 Client is run under some other scheduler, or event loop or
2396 main loop. On GUI applications, for example this may be
2397 desired to used to run the client under the GUI application's
2398 main loop. Typically the GUI application would register an
2399 idle task that calls this function multiple times in a second
2400 to quickly process the SILC specific data.
2402 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2404 * Fixed silc_server_drop() for dropping the supplementary
2405 groups as well, this could cause a security hole on some
2408 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2410 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2413 * Write PID file after dropping privileges. Added -F option
2414 to run server on foreground. A patch by debolaz.
2415 Affected files silcd/server.c, silcd/silcd.c.
2417 * Fixed MOTD to return the MOTD file server name. Affected
2418 file silcd/command.c.
2420 * Added INFO command reply handling to the Irssi SILC Client.
2421 Affected file irssi/src/silc/core/client_ops.c.
2423 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Fixed the silc_idcache_list_* routines to really support
2426 the dynamic list. Fixes a crash. Affected file is
2427 lib/silccore/silcidcache.c.
2429 * Fixed the LIST command reply to really call LIST command's
2430 pending callbacks. Affected file silcd/command_reply.c.
2432 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Update conn->local_entry->nickname after giving NICK
2435 command. Affected file lib/silcclient/command.c.
2437 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2439 * Added the [pid] option to the silcd configuration file
2441 Affected files: serverconfig.[ch] and silcd.c
2443 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Save fingerprint in WHOIS command reply in server.
2446 Affected file silcd/command_reply.c.
2448 * Fixed NICK commands pending callback registration.
2449 Affected file lib/silcclient/command.c.
2451 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Use ++server->cmd_ident when sending commands in server,
2454 instead of random number. Affected file silcd/command.c.
2456 * Fixed GETKEY command reply to call actually GETKEY pending
2457 command callbacks. Affected file silcd/command_reply.c.
2459 * A bit stricter check for nicknames. Check for same nickname
2460 in NICK command also. Affected file silcd/command.c.
2462 * Do not call INFO command everytime client ID changes, only
2463 during first connecting. Affected file lib/silcclient/client.c.
2465 * Set the new nickname only after successful command reply for
2466 NICK command is returned by server. Affected file
2467 lib/silcclient/command.c.
2469 * Remove nicknames from nicklist during server_signoff notify.
2470 Should fix /NAMES bit more. The affected file is
2471 irssi/src/silc/core/silc-channels.c.
2473 * Added `fingerprint' field to the SilcIDListData in the
2474 silcd/idlist.h to hold the fingerprint of the client's
2477 Send the fingerprint of the client's public key in WHOIS
2480 Affected files silcd/command.c, and silcd/idlist.[ch].
2482 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2483 create fingerprint from given data.
2485 * Show the fingerprint of the client's public key in WHOIS.
2486 Affected files irssi/src/module-formats.[ch] and
2487 irssi/src/silc/core/client_ops.c.
2489 * Format the multiple same nicknames also during JOIN and
2490 NICK_CHANGE notifys. Affected file is
2491 lib/silcclient/client_notify.c.
2493 * Do not print error on screen for invalid private message
2494 payload since it can come if someone is sending private
2495 messages with wrong key. Affected file
2496 lib/silccore/silcprivate.c.
2498 * Fixed multiple concurrent /PING crash. Affected file
2499 lib/silcclient/command.c.
2501 * Changed the wrong ID encoding. All IP addresses must be
2502 in MSB first order in encoded format. They were encoded
2503 wrong and was in LSB format. Affected files are
2504 silcd/serverid.c, lib/silcutil/silcutil.c.
2506 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2508 * Call the `connect' client operation through the scheduler
2509 in case of error. Affected file lib/silcclient/client.c.
2511 * Call the `failure' client operation even if the error
2512 occurred locally during a protocol. Affected file is
2513 lib/silcclient/protocol.c.
2515 * Added support of sending LIST command to router from normal
2516 server. This way normal server can get list of all channels
2517 in the network too. Fixed the channel list sending in the
2518 server too. Affected files are silcd/command.c, and
2519 silcd/command_reply.[ch].
2521 * Added silc_server_update_channels_by_server and
2522 silc_server_remove_channels_by_server. They are used during
2523 disconnection of primary router and in backup router protocol.
2524 Affected file silcd/server_util.[ch], silcd/server.c and
2525 silcd/server_backup.c.
2527 * Fixed channel adding to global list in IDENTIFY command
2528 reply in server. Affected file silcd/command_reply.c.
2530 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * If the incoming packet type is REKEY or REKEY_DONE process
2533 that packet always synchronously. Fixes yet another MAC
2534 failed error on slow (dialup) connections. Affected file
2535 lib/silcclient/client.c and silcd/server.c.
2537 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Call check_version SKE callback for initiator too. Affected
2540 file lib/silcske/silcske.c.
2542 * Implemented fix for security hole found in the SKE that was
2543 fixed in the specification few days back; the initiator's
2544 public key is now added to the HASH value computation.
2545 Added backwards support for the old way of doing it too, for
2546 old clients and old servers. Affected file is
2547 lib/silcske/silcske.c.
2549 * Enabled mutual authentication by default in SKE. If initiator
2550 is not providing mutual authentication the responder will
2551 force it. This will provide the proof of posession of the
2552 private key for responder. The affected files are
2553 lib/silcclient/protocol.c and silcd/protocol.c.
2555 * Do not cache anymore the server's public key during SKE.
2556 We do mutual authentication so the proof of posession of
2557 private key is done, and if the server is authenticated in
2558 conn auth protocol with public key we must have the public
2559 key already. Affected file silcd/protocol.c.
2561 * Added new global debug variable: silc_debug_hexdump. If
2562 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2563 file lib/silcutil/silclog.[ch].
2565 * Fixed compilation warning due to char * -> const char *.
2566 Affected files lib/silcutil/silcnet.h, and
2567 lib/silccore/silcauth.[ch].
2569 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Fixed CMODE command when new channel key was created. If
2572 the creation failed the old key was removed. Next time giving
2573 same command would crash the server since the old key was
2574 freed already. Affected file silcd/command.c.
2576 * Fixed the silc_server_announce_get_channels to not crash
2577 on reconnect. Affected file silcd/server.c.
2579 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Added silc_log_set_debug_string function to set a regex
2582 string to match for debug output. Only the function names,
2583 or filenames matching the given debug string is actually
2584 printed. This way it is possible to filter out those debug
2585 strings that user is not interested in.
2587 Fixed a bug in silc_string_regexify.
2589 Affected files lib/silcutil/silclog.[ch], and
2590 lib/silcutil/unix/silcunixutil.c.
2592 * Changed the -d options in both server and Irssi SILC client
2593 to take the debug string as argument. Affected files
2594 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2596 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Added silc_hash_babbleprint to create a Bubble Babble
2599 Encoded fingerprint. The encoding is developed by Antti
2600 Huima (draft-huima-babble-01.txt), and it creates human
2601 readable strings out of binary data. Affected file
2602 lib/silccrypt/silchash.[ch].
2604 * Print the babble print now in addition of fingerprint as well
2605 in Irssi SILC client. Affected files are
2606 irssi/src/fe-common/silc/module-formats.[ch],

2609 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Fixed a security problem found in SKE. The initiator's
2612 public key too is now added to the HASH hash value creation
2613 which is signed by the responder to create the SIGN value.
2614 This will prevent anyone in the middle to lie to the responder
2615 about the initiator's public key. If this is done now, the
2616 man in the middle will get caught. Updated the protocol
2619 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Better installation directory handling. Configure module
2622 paths and other paths automatically to example_silc* files
2623 in doc/. A patch by toma.
2625 * Fixed compiler warning from MPI library, and from SILC RNG.
2628 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2629 It can be configured with ./configure. A patch by toma.
2631 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Find correct make to use in prepare-clean. A patch by
2634 toma. Affected file prepare-clean.

2653 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Added silc_pkcs_public_key_compare to compare two
2656 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2658 * Check that the client who set the founder mode on the
2659 channel is the same client that is giving the founder
2660 mode to itself. It is done by comparing the saved public
2661 key (it is saved even in the authentication is passphrase).

2669 * Process the DISCONNECT packet through scheduler in the
2670 client library. Affected file lib/silcclient/client.c.
2672 * Fixed the silc_client_packet_parse to not to increase
2673 the packet sequence number if the conn->sock and the
2674 current socket connection is not same. This can happen
2675 for example during key agreement when the conn includes
2676 multiple socket connections (listeners). Affected file
2677 lib/silcclient/client.c.
2679 * The sender of the file transfer request now provides also
2680 the pointer (listener) for the key exchange protocol. If
2681 the listener cannot be created then it sends empty key
2682 agreement and lets the receiver provide the listener.
2684 Added `local_ip' and `local_port' arguments to the
2685 silc_client_file_send. If they are provided they are used,
2686 if not then it will attempt to find local IP address, if
2687 not found or bind fails then the remote client will provide
2690 Affected files are lib/silcclient/client_ftp.c and
2691 lib/silcclient/silcapi.h.
2693 * Extended the FILE SEND command to support defining the
2694 local IP and port for key exchange listener. They are

2699 * Defined to WHOIS command reply the sending of fingerprint
2700 of the client's public key (if the proof of posession of the
2701 corresponding private key is verified by the server).
2702 Updated to the protocol specification.
2704 * Added support of receiving the client's public key's
2705 fingerprint in command reply in client library. Affected
2706 file is lib/silcclient/command_reply.c, and
2707 lib/silcclient/idlist.[ch].
2709 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2766 preserve the WHOWAS info for the client. Affected file
2767 silcd/server_util.c.
2769 * Fixed SERVER_SIGNOFF notify handling in the server. The
2770 server is now able to process incoming SERVER_SIGNOFF notify
2771 for a server that it doesn't even know about. It will remove
2772 the clients provided in the notify. Affected file
2773 silcd/packet_receive.c.
2775 * Check for partial packet in data queue after every packet that
2776 was found from the queue. Return and wait for more data if
2777 there is partial data in queue. Affected file is
2778 lib/silccore/silcpacket.c.
2780 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2795 irssi/src/fe-common/silc/module-formats.[ch].
2797 * Wrote a help file for FILE command.
2799 * Added silc_rng_global_get_byte_fast to get not-so-secure
2800 random data as fast as possible. Random data is read from
2801 /dev/urandom if available and from the SILC RNG if not
2802 available. It is used in padding generation. Affected file
2803 lib/silccrypt/silcrng.[ch].
2805 * All packets in client library are now processed synchronously.
2806 Optimized packet processing a lot. Affected file
2807 lib/silcclient/client.c.
2809 * All server connection packets are processing synchronously
2810 now in server, to optimize packet processing. Affected file
2813 * Include files are installed now only in Toolkit distribution
2814 if make install is given. Affected files: all Makefile.am's.
2816 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2818 * Assure that silc_client_notify_by_server_resolve does not
2819 resolve the client information multiple times. If it cannot
2820 be found by the first it cannot be found at all. Affected
2821 file lib/silcclient/client_notify.c.
2823 * Fixed WHOWAS command reply calling. Affected file
2824 lib/silcclient/command_reply.c.
2826 * Removed all references to silc_idlist_get_client from the
2827 Irssi SILC client since that call is internal call used by
2828 the library. The Irssi SILC client will use now client
2829 retrieval functions found in silcapi.h.
2831 * Fixed a bug in resolving nickname info before sending
2832 private message. It used freed memory. Affected file
2833 irssi/src/silc/core/silc-servers.c.
2835 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2837 * Assure my_channels statistics cannot go negative in server.
2838 Affected files silcd/server.c, silcd/server_util.c.

2854 * Added silc_net_localip to return local host's IP address.
2855 Affected file lib/silcutil/silcnet.[ch].
2857 * If key exchange or rekey protocol is active for a connection
2858 parse all packets syncronously since there might be packets
2859 in packet queue that we are not able to process without first
2860 processing packets before them. Affected file silcd/server,
2861 lib/silcclient/client.c.
2863 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2864 whether library should continue processing the packet.
2865 Affected file lib/silccore/silcpacket.h.
2867 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2911 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2912 is incomplete and is being resolved, it won't be resolved
2915 Make sure also that USERS command reply does not resolve
2916 twice information. Affected file is
2917 lib/silcclient/command_reply.c.
2919 Make sure that silc_client_get_clients_by_list does not
2920 resolve twice same information.
2922 * Check for valid client->id in the silc_server_free_client_data.
2923 Affected file silcd/server.c.
2925 * Fixed /GETKEY nick@server not to crash if the server entry
2926 is not found. Affected file lib/silcclient/command.c.
2928 * Fixed the silc_server_check_cmode_rights to check the

2936 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Call the silc_server_udpate_servers_by_server in the
2939 primary router that comes back online in the backup resuming
2940 protocol. Otherwise it routes packets wrong. Affected file
2941 silcd/server_util.[ch], silcd/server_backup.c.
2943 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2946 lib/silcutil/silcbuffmt.[ch].
2948 * Redefined the SILC packet header to include the padding
2949 length. Affected file lib/silccore/silcpacket.[ch].
2951 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2952 length for maximum padding up to 128 bytes). Affected
2953 file lib/silccore/silcpacket.h.
2955 * Removed all backwards support for old 0.5.x MAC thingies.
2956 The SILC packet header change makes it impossible to be
2957 backwards compatible.
2959 * Send the ENDING packet with timeout in the backup resuming
2960 protocol. This is to assure that all routers has connected
2961 to the primary router. Affected file silcd/server_backup.c.
2963 * Changed the RNG to take the first IV from random data. It
2964 used to take it from zero actually. Changed the RNG also
2965 to use /dev/urandom during session. /dev/random is used
2966 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2968 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Changed the SILC packet header to have the first two bytes
2971 (the packet length) encrypted. Affected files aroung the
2972 code tree, lib/silccore/silcpacket.[ch]. Removed the
2973 SilcPacketCheckDecrypt callback. It is not needed anymore
2974 since the silc_packet_receive_process will determine now
2975 whether the packet is normal or special.
2977 * Implemented the unidirectional MAC keys. Affected files
2978 lib/silcske/silcske.c, silcd/protocol.c and
2979 lib/silcclient/protocol.c.

2986 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Allow backup router to announce servers. All servers
2989 announced by backup router are added to the global list
2990 automatically. Update hte server's socket to our primary
2991 router also when backup router announces a server.
2992 Affected file silcd/packet_receive.c.
2994 * Do not update the client->router in the function
2995 silc_server_udpate_clients_by_server if the client is on
2996 global list. We might fail to find any specific server
2997 for locally connected clients and local cell clients. They
2998 should still use the `from' and not `to' as client->router.
2999 This fixes backup router resuming protocol. Affected file
3000 silcd/server_util.c.
3002 * Decrease channel statistics count only if the channel
3003 deletion worked. Affected files are silcd/server.c and
3004 silcd/server_util.c.
3006 * Added silc_server_update_servers_by_server to update origin
3007 of all server entries. Used during backup router protocol.

3014 lib/silccrypt/silchmac.c.
3016 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * Assure that router cannot reroute the same channel message
3019 to the sender. Affected file silcd/packet_receive.c.
3021 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Made better checks that the channel message is not sent
3024 to the router it came from. Affected file is
3025 silcd/packet_send.c. Fixed memory leak too.
3027 * Announce informations for incoming router connection, but
3028 only after checking if it is replaced by backup router.
3029 Affected file silcd/packet_receive.c.
3031 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Fixed the backup resuming protocol to work in multiple
3034 router environment. Affected file silcd/server_backup.c.
3036 * Route packet only to one router in the function
3037 silc_server_packet_send_to_channel. Affected file is
3038 silcd/packet_send.c.
3040 * Fixed silc_server_send_notify_dest to set the broadcast
3041 flag. Fixed the silc_server_send_notify_topic to actually
3042 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3043 Affected file silcd/packet_send.c.
3045 * Changed the SFTP Filesystem interface. Changed the
3046 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3047 the filesystem operation function. The SilcSFTPFilesystem
3048 is now a context that is allocated by all filesystem allocation
3049 functions and it already includes the operations structure
3050 and filesystem specific context. It is given as argument
3051 now to the silc_sftp_server_start. This made the interface
3052 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3053 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3055 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Changed the backup router adding and getting interfaces
3058 in the server. The router that will be replaced by the
3059 specified backup router is now sent as argument. Affected
3060 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3063 * Added silc_net_addr2bin_ne to return the binary form of
3064 the IP address in network byte order. Affected files
3065 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3067 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Check for existing server ID in silc_server_new_server
3070 and in silc_server_connect_to_router_final and remove the
3071 old entry if it exists. Affected file silcd/packet_receive.c,
3074 * Send the channel message always to only one router, either
3075 in upstream or downstream. Affected file is
3076 silcd/packet_send.c.
3078 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Wrote the definition of the backup resuming protocol to the
3081 protocol specification.
3083 * Removed one redundant channel key generation from normal
3084 server during joining procedure. Removed one redundant
3085 channel key sending from server to router during joining
3086 procedure. Affected file silcd/command.c.
3088 * Made minor bugfixes to the backup router resuming protocol.
3089 Affected file silcd/server_backup.c, server.c.
3091 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3098 resume the primary router position in the cell after the
3099 primary router comes back online. Affected files
3100 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3101 and silcd/server_util.[ch].
3103 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3105 * Sleep two (2) seconds after sending QUIT command to server.
3106 Affected file lib/silcclient/command.c.
3108 * Assure that if outgoing data buffer is pending do not force
3109 send any data. Affected file silcd/packet_send.c.
3111 * Assure that if outgoing data buffer is pending do not force
3112 send any data. Affected file lib/silcclient/client.c.
3114 * Implemented the backup router support when the primary router
3115 goes down. The servers and routers can now use the backup
3116 router as new primary router without loosing connectivity.
3118 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3120 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3121 in the server to indicate disabled entry. All data read
3122 from the connection will be ignored and no data is sent
3123 for entry that is disabled. Affected files are
3124 silcd/idlist.h, silcd/server.c.
3126 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3128 * Created SFTP client and server test programs in the
3129 lib/silcsftp/tests directory.
3131 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Implemented memory filesystem (virtual filesystem) for
3134 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3137 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Implemented the SFTP (SSH File Transfer Protocol) to the
3140 lib/silcsftp. It includes SFTP client and SFTP server
3143 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Moved lib/silccore/silcprotocol.[ch] to the
3146 lib/silcutil library.
3148 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3149 take variable argument list pointer as argument. Affected
3150 file lib/silcutil/silcbuffmt.[ch].
3152 * Added silc_buffer_set function that is used to set data
3153 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3154 Affected file lib/silcutil/silcbuffer.h.
3156 * Changed various routines in the core library to use the new
3157 silc_buffer_set instead of allocating new buffer only for
3160 * Added 64-bit value formatting and unformatting support to the
3161 silc_buffer_[un]format routines. Affected file is
3162 lib/silcutil/silcbuffmt.[ch].
3164 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3165 to includes/bitmove.h.
3167 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3169 * Fixed channel user mode saving in client library. Affected
3170 file lib/silcclient/command[_reply].c.
3172 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Defined the file transfer to the SILC Protocol. Added
3175 new packet type SILC_PACKET_FTP and defined File Transfer
3176 Payload. The mandatory file transfer protocol is SFTP
3177 (SSH File Transfer Protocol). Affected file in addition
3178 of the internet draft is lib/silccore/silcpacket.h.
3180 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3181 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3182 is used as part of backup router protocol when the primary
3183 router of the cell is back online and wishes to resume
3184 the position as primary router.
3186 * Redefined the MAC generation keys in the protocol. The
3187 same key is not used anymore in both direction. Both
3188 direction will now use different keys for sending and
3189 receiving. This fixes a potential security flaw. This
3190 change causes incompatibilities in the protocol.
3192 * Redefined also the MAC computation from the packet.
3193 An packet sequence number is now added to the MAC
3194 computation. This prevents possible replay attacks against
3195 the protocol. This change too causes incompatibilities
3198 Added `sequence' field to the SilcPacketContext to hold
3199 the current sequence number for the packet.
3201 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Added `created' field to the SilcIDListData in the file
3204 silcd/idlist.h to indicate the time when the entry was
3207 * Added `created' field to the SilcChannelEntry too. Affected
3208 file silcd/idlist.h.
3210 * Added `creation_time' aguments to all the announcement functions
3211 in the server. If it is provided then only the entries that
3212 was created after the provided time frame are actually
3213 announced. Affected file silcd/server.[ch].
3215 * The protocol says that the Channel ID's IP address must be
3216 based on the router's IP address. Added check for this in
3217 the silc_server_new_channel when processing incoming New Channel
3218 Payload. Affected file silcd/packet_receive.c.
3220 * Print out the correct version with --version in SILC client.
3221 Affected file irssi/src/silc/core/silc-core.c.
3223 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3225 * Fixed WHOWAS command to check for completnes of the client
3226 entry always, not just when the command is coming from client.
3227 Affected file silcd/command.c.
3229 * Added new function silc_server_packet_queue_purge to purge the
3230 outgoing data queue to the network. After the function returns
3231 it is guaranteed that the outgoing packet queue is empty.
3232 Affected file silcd/packet_send.[ch].
3234 * Purge the outgoing packet queue in the rekey protocol's final
3235 callback to assure that all rekey packets go to the network
3236 before quitting the protocol. Affected file silcd/server.c.
3238 * Added silc_client_packet_queue_parse as similar function as
3239 in server to the client library. The affected file is
3240 lib/silcclient/client.c.
3242 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3244 * Splitted silcd/server.c and created silcd/server_util.[ch]
3245 for utility functions.
3247 * Added new socket flag SILC_SF_DISABLED to indicate that the
3248 connection is open but nothing can be sent to or received from
3249 the connection. Affected file lib/silcutil/silsockconn.[ch].
3250 The checking for disabled socket is checked in the low level
3251 silc_socket_write and silc_socket_read functions.
3253 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * Allow only nicknames and channel names that fits into the
3256 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3258 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3260 * When processing JOIN command reply in server check that if
3261 the channel exists in our global list we'll move it the local
3262 list. Affected file silcd/command_reply.c.
3264 * Fixed the check whether client is joined on the channel already
3265 in JOIN command. Affected file lib/silcclient/command.c.
3267 * Fixed the JOIN command reply to check whether the channel
3268 already exists. Affected file lib/silcclient/command_reply.c.
3270 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3272 * Added silc_ske_status_string to map the SKE error numbers
3273 to readable strings. The affected files are
3274 lib/silcske/silcske[_status].[ch].
3276 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * Do not show the private channels on the WHOIS channel list
3279 as it is not allowed by the protocol. The affected file is
3282 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * Assure that the packet length digged from the actual packet
3285 is something sensible in the silc_packet_decrypt_rest_special
3286 in lib/silccrypt/silcpacket.c.
3288 * Free and NULL the allocated pointer in silc_hmac_alloc if
3289 the HMAC allocation fails. The affected file is
3290 lib/silccrypt/silchmac.c.
3292 * Print the selected security properties to the log files in
3293 the server. Affected file silcd/protocol.c.
3295 * Add SKE's reference counter even if calling the completion
3296 callback manually. Otherwise it goes negative, although it
3297 does not cause any problems. The affected file is
3298 lib/silcske/silcske.c.
3300 * Remove the client entry with short timeout after giving the
3301 KILL command. Affected file lib/silcclient/command.c.
3303 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3304 case all found clients are already disconnected (WHOWAS would
3305 found them) in the server. Affected file silcd/command.c.
3307 * Update the last_receive (time of last data received) to be
3308 updated only when received private or channel message so that
3309 the idle time showed in WHOIS makes more sense.
3311 * Added boolean field `valid' in to the SilcClientEntry in the
3312 client library to indicate whether the entry is valid or not.
3313 This fixes the nickname change bug on channel when changing
3314 the nickname to be same than the old (like nick to Nick) the
3315 nickname formatter doesn't set the new nick anymore to Nick@host.
3316 Affected file lib/silcclient/idlist.[ch].
3318 * Now actually fixed the nickname changing on disconnection.
3319 Added new function silc_change_nick to the Irssi SILC Client.
3320 Affected file irssi/src/silc/core/client_ops.c,
3321 irssi/src/silc/core/silc-nicklist.[ch].
3323 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Check that the public key exists in the GETKEY command before
3326 trying to encode it. Affected file silcd/command.c.
3328 * Print some notifications on received public keys with GETKEY
3329 command in the Irssi SILC Client. Affected files are
3330 irssi/src/fe-common/silc/module-formats.[ch],
3331 irssi/src/silc/core/client_ops.c.
3333 * Use IDENTIFY command to resolve the server information in the
3334 GETKEY command instead of INFO command. Affected file
3335 lib/silcclient/command.c.
3337 * All command reply functions in the client library now calls
3338 the pending command reply callbacks even if an error has
3339 occurred. The server has done this a long time and now it was
3340 time to move the client library to this as well. Now all
3341 errors can be delivered back to the pending command reply
3342 callbacks if necessary. Affected files are
3343 lib/silcclient/command[_reply].[ch].
3345 * Change the nickname on disconnection back to the username
3346 because in reconnect the server will enforce it to it anyway.
3347 Affected file irssi/src/silc/core/silc-servers.c.
3349 * Fixed a config file parsing bug in the Irssi SILC client.
3350 Affected file irssi/src/silc/core/clientconfig.c.
3352 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * When printing the channel mode on JOIN, verify that the
3355 channel key and channel's HMAC are valid. Affected file
3356 irssi/src/silc/core/client_ops.c.
3358 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3361 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3362 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3364 * Removed channel key rekey task deleting from the function
3365 silc_server_save_channel_key. Affected file silcd/server.c.
3366 Added explicit timeout task context instead that is used to
3367 delete the task if we are registering a new task before the
3368 new task has elapsed.
3370 * When channel key rekey occurs the client library now saves
3371 the old channel key for a short period of time (10 seconds) and
3372 is able to use it in case some is still sending channel
3373 messages encrypted with the old key after the rekey. Affected
3374 file lib/silcclient/[idlist.h|client_channel.c].
3376 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3378 * Added check to the silc_server_new_id_real to not accept
3379 new ID if it is the sender's own ID. Affected file is
3380 silcd/packet_receive.c.
3382 * Assure that we do not announce ourself or the one we've
3383 sending our announcements when we're router and are announcing
3384 servers to our primary router. Affected file silcd/server.c.
3386 * Fixed silc_server_command_identify_check_client to assemble
3387 correct WHOIS packet. It send corrupted WHOIS packet and
3388 caused problem with router to router connections. Affected
3389 file silcd/command.c.
3391 Fixed also silc_server_command_whois_check the same way
3392 as for the IDENTIFY command.
3394 * Added new SilcIDListStatus to the server in the SilcIDListData
3395 structure. The status now includes the current status of
3396 the entry (like registered, resolved etc.). Affected file
3397 silcd/idlist.[ch]. Defined a bunch of different status types
3398 as well. This replaced the old boolean registered field as well.
3400 Added resolve_cmd_ident field to the SilcClientEntry structure
3401 too so that if the entry is for example being resolved so
3402 another command may attach to the same pending command reply
3403 without requiring to resolve the same entry again. This concept
3404 should optimize the WHOIS and the IDENTIFY resolving under
3405 heavy load by taking away unnecessary resolving for entries
3406 that are being resolved already.
3408 Added support for adding multiple pending commands for one
3409 command idenfier. Affected file silcd/command[_reply].[ch].
3411 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3412 before deleting the data. Otherwise the hash table will have
3413 freed data in comparison functions. Affected file is
3414 silcd/command_reply.c.
3416 * Fixed silc_idlist_replace_client_id to add the new entry to
3417 the cache with NULL nickname. Otherwise there will be invalid
3418 memory as the nickname after the nickname is freed. Affected
3419 file silcd/packet_receive.c.
3421 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3422 saved into wrong slots because the previous number of entries
3423 was not taken into account. Affected file silcd/idlist.c.
3424 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3426 * If we are router and we receive JOIN notify to a channel that
3427 does not have any users then notified client is marked as the
3428 channel founder, as it is it. The affected file is
3429 silcd/packet_receive.c
3431 * Added to the extended hash table API's table_del_*ext functions
3432 the destructor as argument too, so that the caller can decide
3433 which destructor to use or whether to use destructor at all.
3434 Affected file lib/silcutil/silchashtable.[ch].
3436 * Fixed ID Cache purging. It actually deleted the entries from
3437 the hash table after the data was freed. The hash table ended
3438 up comparing freed memory. The affected file is
3439 lib/silccore/silcidcache.c.
3441 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Fixed Irssi SILC client's KILL command's HELP syntax.
3445 * The USERS command now resolves the detailed user information
3446 if the userinfo field is missing. Affected file is
3447 lib/silcclient/command_reply.c.
3449 * Do not print error in silc_file_read if the read file does
3450 not exist. Just silently return NULL. Affected file is
3451 lib/silcutil/silcutil.c.
3453 * Fixed the silc_log_output to not wine about NULL filename
3454 and to not create some bogus " " filename. Affected file is
3455 lib/silcutil/silclog.c.
3457 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Fixed various printing bugs on the user interface in the
3460 Irssi SILC Client. Minor changes that were forgotten from
3463 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3465 * Fixed the configure.in.pre and the compilation and distribution
3466 environment to support the new autoconf 2.52. That version is
3467 now required to compile the CVS trunk.
3469 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3471 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3472 to generally parse user@fqdn format strings. Affected file
3473 lib/silcutil/silcutil.c.
3475 * Added nickname_format and nickname_force_format fields to the
3476 SilcClientParams structure. The first one defines the format
3477 for the nicknames that the library will enforce if the receives
3478 multiple same nicknames. The second one is boolean value and
3479 can be used to force the library to always enforce the format
3480 to the nicknames regardles whether there are multiple nicknames
3481 or not. This configurable formatting was employed to flexibly
3482 support accessing multiple nicknames from the user interface.
3483 The userinterface can now set the nicknames to what ever format
3484 they prefer. Affected file lib/silcclient/silcapi.h.
3486 Added function silc_client_nickname_format to the file
3487 lib/silcclient/idlist.c. It performs the nickname formatting.
3489 Added new field `hostname´ to the SilcClientEntry context.
3490 It holds the hostname of the client. Affected file is
3491 lib/silcclient/idlist.h.
3493 * Irssi SILC Client sets the nicknames in nick@hostn format.
3494 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3495 irssi/src/silc/core/silc-core.c.
3497 The WHOIS printing now also shows both the real nickname and
3498 the formatted nickname so that user knows how to access the
3499 user if there are multiple same nicknames cached. Affected
3500 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3501 printing formatting too to take the hostname now as a separate
3502 argument. The Affected file is
3503 irssi/src/fe-common/silc/modules-formats.[ch].
3505 * Changed the silc_client_get_clients_local to accept the formatted
3506 nickname as argument. It accepts the real nickname too but the
3507 formatted nickname can be used to find the true entry from
3508 multiple entries. Affected file lib/silcclient/silcapi.h and
3509 lib/silcclient/idlist.c.
3511 * Added nickname_format_parse field to the SilcClientParams.
3512 It is a callback function provided by the application to parse
3513 the nickname out of the formatted nickname string. The library
3514 calls it to get the nickname from the formatted string. Since
3515 the application generally knows better the format of the nickname
3516 string it parses it instead of the library, even though library
3517 encodes the formatted string. If the callback function is not
3518 provided then the library will use the string as is. The
3519 affected file is lib/silcclient/silcapi.h.
3521 * All the nickname strings passed to the client library in
3522 commands are now expected to be formatted nickname strings.
3523 If the command does not support the formatted nickname string
3524 it will assume that the sent string is the actual nickname.
3525 Affected file lib/silcclient/command.c.
3527 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3529 * Added public key authentication support to OPER and SILCOPER
3530 commands in the client library. Affected file is
3531 lib/silcclient/command.c.
3533 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3535 * Changed the get_auth_methdod client operation to be asynchronous.
3536 It can be async if the application resolves the authentication
3537 method from the server during the negotiation. Added new
3538 SilcGetAuthMeth completion callback that the application will
3539 call after resolving the authentication method.
3541 Added function silc_client_request_authentication_method that
3542 the application can use to resolve the authentication method
3543 from the server. Added also SilcConnectionAuthRequest callback
3544 that the library will call after the server has replied. The
3545 application can call this function if it does not know the
3546 current authentication method.
3548 Affected files are lib/silcclient/client.c and
3549 lib/silcclient/silcapi.h.
3551 * The Irssi SILC client now automatically resolves the authentication
3552 method incase any configuration information is not present (and
3553 currently there never is). The affected file is
3554 irssi/src/silc/core/client_ops.c.
3556 * Fixed public key authentication from the client library.
3557 Affected file lib/silcclient/protocol.c. Changed also the
3558 protocol specification about the public key authentication in
3559 the connection authentication protocol. The actual data to be
3560 signed is now computed with a hash function before signing.
3562 * Fixed the public key authentication from the server as well.
3563 Affected file silcd/protocol.c.
3565 * Removed the mlock()'s from the memory allocation routines.
3566 Affected file lib/silcutil/silcmemory.c. The ./configure does
3567 not check anymore for the mlock(). Affected file is
3570 * Fixed USERS command in server to allow the execution of the
3571 command for private and secret channels if the client sending
3572 the command is on the channel. Affected file silcd/command.c.
3574 * Fixed silc_client_get_clients_local to return the clients
3575 count correctly. It could return wrong value. Affected file
3576 lib/silcclient/idlist.c.
3578 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3580 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3581 types. The assembler optimizations seemed not to like 64-bit
3582 data types. The assmebler optimizations thus are now enabled
3583 also for BSD systems as opposed to only enable them for Linux.
3585 * Do not check for threads at all on BSD systems. Affected
3586 file configure.in.pre.
3588 * Removed -n and -h options from the Irssi SILC Client since
3589 they are not used in silc.
3591 * Fixed the prime generation to assure that the first digit
3592 of the generated random number is not zero since our conversion
3593 routines does not like number strings that starts with zero
3594 digit. If zero digit is seen the random number is regenerated.
3595 This caused some corrupted RSA keys when the zero first digit
3596 was met. Affected file lib/silcmath/silcprimegen.c.
3598 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3600 * Fixed WIN32 configuration in the ./configure script.
3601 Fixed to include xti.h on environments that has it.
3602 Patches by Carsten Ilchmann and andrew.
3604 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3606 * Changed the silc_id_create_client_id to be collision
3607 resistant. It is now assured that there cannot be created
3608 two same client ID's. I suspect that some weird bugs in
3609 the server were actually caused by duplicate Client IDs.
3610 Affected file silcd/serverid.[ch]. A router receiving
3611 new ID now also assures and informs the sending server
3612 if the ID caused collision.
3614 * Changed the silc_id_create_channel_id to also assure that
3615 there are no collisions.
3617 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3619 * Statement about ignoring the Mutual Authentication flag when
3620 performing rekey with PFS was a bit misleading. It is ignored
3621 if it was set in the initial negotiation, it cannot be even
3622 set in the rekey. Fixed in the ke-auth draft. Started the
3623 new versions of the protocol drafts in the doc/.
3625 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3627 * Fixed a bug in silc_client_command_identify_save when saving
3628 new channel information. The channel name was no duplicated
3629 and caused crash on exit. Affected file is
3630 lib/silcclient/command_reply.c.
3632 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3634 * Fixed the getkey command handling in the server. Send just
3635 empty OK reply to the sender if the key could not be fetched
3636 (but everything else was ok, like the key just was not available).
3637 Changed the public key parameter to optional in the protocol
3638 specs so that empty OK reply can be sent. Affected file
3641 Added a message to Irssi SILC client to tell to user if the
3642 server did not return a public key.
3644 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3646 * Fixed a channel key regeneration bug. It registered new
3647 timeout tasks exponentially until all system resources were
3648 used. Affected file silcd/server.c.
3650 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3652 * Added the SILC Document generator to the scripts/silcdoc.
3653 It can be used to generate the Toolkit Reference Manual out
3654 of the source tree. Internally it will also use the RoboDoc
3655 generator now imported in util/robodoc.
3657 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Added couple of return's in rekey protocol if error orccurred
3660 during the protocol. The execution must be terminated.
3661 Affected file silcd/protocol.c. Also, terminate the protocol
3662 always with timeout.
3664 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3666 * The client's Client ID was created initally from the wrong
3667 nickname (it could have been in format nick@host) in the
3668 silc_server_new_client. Affected file silcd/packet_receive.c
3670 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Added some SILC_LOG_ERROR's to various error conditions
3673 if client could not be added to ID cache. Affected files
3674 silcd/packet_receive.c and silcd/server.c.
3676 * When client's sock->user_data is freed, NULL also the
3677 client->router and client->connection pointers. Added check
3678 for these pointers being NULL to various places around the
3679 code. Affected file silcd/server.c.
3681 * Added client->data.registered == TRUE checks to various
3682 places around the code to assure that unregistered client's
3683 are not handled when it is not allowed. Affected file
3686 * Added `bool registered' fields to all
3687 silc_idlist_[server|client]_get_* routines to indicate whether
3688 the fetched client needs to be registered or not. Affected
3689 file silcd/idlist.[ch].
3691 * Add your own entry as registered to the ID cache in the
3692 server. Affected file server.c.
3694 * Fixed a bug in silc_server_new_server. The SilcServer was
3695 set as the new server's context instead of SilcServerEntry.
3696 This naturally caused some weird bugs.
3698 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3700 * Do not delete the channel rekey task when adding it
3701 for in silc_server_create_channel_key.
3703 * Changed the silc_server_create_channel_key to return
3704 TRUE or FALSE to indicate the success of the channel key
3707 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3709 * Fixed MSVC++ project files and added missing files to

3715 does not have it defined. Affected files are
3716 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3718 * Fixed buffer overflow from Irssi SILC Client. Affected
3719 file irssi/src/fe-common/core/themes.c.
3721 * Fixed double free in client library in the file
3722 lib/silcclient/client.c when disconnecting from server.
3724 * Applied double free patch from cras to Irssi SILC client.
3725 Affected files irssi/src/core/[modules/expandos].c
3727 * Fixed the disconnection handling to Irssi SILC Client.
3728 The application must call silc_client_close_connection
3729 in ops->connect client operation in case of failure of
3730 the connection. Affected file is
3731 irssi/src/silc/core/client_ops.c.
3733 * Do not set sock->protocol to NULL in the function
3734 silc_client_close_connection after executing the protocol's
3735 final callback since the sock might not be valid anymore.
3736 Affected file lib/silcclient/client.c.
3738 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3740 * Do not enable SILC_THREADS if the linking with libpthread
3741 did not happen. Affected file configure.in.pre.
3743 * Added notion to protocol specification that server must
3744 verify the sent authentication payload with CMODE when
3745 setting the channel founder key. Implemented it to the
3746 server. Affected file silcd/command.c.
3748 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3750 * Added _EXTRA_DIST SILC distribution variable to the
3751 distributions file. It is used to conditionally add extra
3752 files or directories to the specific distribution. Affected
3753 files ./prepare, Makefile.am.pre and distributions.
3755 Removed the `_' from the start of the distribution names.
3758 * Added README.WIN32 for instructions to compile the Toolkit
3761 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3763 * Fixed a double free in disconnection in the server. Affected
3764 file is silcd/server.c.
3766 * Fixed the lib/silcske/groups.c to work now also with GMP
3767 MP library. The string conversion did not work when using
3768 specific base and the base is indicated in the string as well.
3770 * Created win32/ directory which now includes MSVC++ specific
3771 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3772 It will appear only in the toolkit distribution
3774 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3776 * Changed the key material distribution function in case when
3777 the hash output is too short. The data is now concatenated
3778 a bit differently than it used to. Made the change to the
3779 SKE protocol specification.
3781 * Added better GMP detection to configure.in.pre. A patch
3784 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3786 * Fixed a minor bug in SKE that might cause some problem on
3787 some platforms. Affected file lib/silcske/silcske.c.
3789 * Added the cookie checking for initiator in the SKE. It checks
3790 that the responder returns the sent cookie unmodified. The
3791 affected file is lib/silcske/silcske.c. Added new SKE
3792 error type INVALID_COOKIE that can be sent during the
3793 negotiation. Fixed some memory leaks as well.
3795 * Added the "invalid cookie" error message to Irssi SILC client's
3798 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * Added `task_max' field to the SilcClientParams to indicate
3801 the maximum tasks the scheduler can handle. If set to zero,
3802 default values are used. Affected file lib/silcclient/silcapi.h.
3804 * Fixed memory leaks in silc_client_close_connection. Affected
3805 file lib/silcclient/client.c.
3807 * Added silc_client_del_client_entry to client library to free
3808 all memory of given client entry. Affected file is
3809 lib/silcclient/idlist.[ch].
3811 * Added new functions silc_client_del_channel and
3812 silc_client_del_server to delete channel and server entries.
3813 Affected file lib/silcclient/[silcapi.h/idlist.c].
3815 * Removed silc_client_del_client_by_id from silcapi.h.
3817 * Fixed the INFO command to return the server's own info
3818 correctly when querying by Server ID. Affected file is
3821 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3823 * Removed the non-blocking settings in WIN32 code in the
3824 silc_sock_[read/write] and added SleepEx instead. Affected
3825 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3826 of input data is now checked with FIONREAD and ioctlsocket.
3828 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3830 * Call silc_schedule_task_del_by_context in the
3831 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3832 Affected file lib/silccore/silcprotocol.c.
3834 * Call silc_protocol_cancel for active protocols in the
3835 silc_server_close_connection if the funtion
3836 silc_server_free_sock_user_data has not been called.
3837 Affected file silcd/server.c.
3839 * Generic tasks cannot be deleted using the del_by_fd
3840 task deleting function since generic tasks does not match
3841 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3843 * Added a notion to SILCOPER help file that the SILCOPER works
3844 only on router server, not on normal server.
3846 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3848 * Added for WIN32 support for the new scheduler as well.
3849 Affected file lib/silcutil/win32/silcwin32schedule.c.
3851 * Fixed the SHA1 implementation to work on various platforms.
3853 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3855 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3856 API. It is part of the scheduler now. Everything else is
3857 as previously but some functions has changed their names.
3858 Checkout the lib/silcutil/silcschedule.h for the interface.
3859 Updated all applications to use the new interface. Affected
3860 files are lib/silcutil/silcschedule.[ch].
3862 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3864 * Found a bug in the SKE implementation. The HASH value,
3865 specified by the protocol, was not computed correctly. The
3866 public key of the responder was not added to the computation
3867 even though it is mandatory. Affected file lib/silcske/silcske.c.
3868 This unfortunately causes incompatibilities with older
3869 clients and servers.
3871 * Added WIN32 specific network init and uninit functions:
3872 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3873 the Winsock2. Affected file lib/silcutil/silcnet.h and
3874 lib/silcutil/win32/silcwin32net.c.
3876 * Set the socket always to nonblocking mode on WIN32 after
3877 reading data or writing data. Affected file is
3878 lib/silcutil/win32/silcwin32sockconn.c.
3880 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3882 * Fixed various compilation problems under WIN32. Affected
3883 files lib/silcutil/win32/silcwin32thread.c and
3884 lib/silcutil/win32/silcwin32schedule.c.
3886 * Removed all _internal.h #includes from public header
3887 files. Internal headers must never be included from
3890 Removed also the lib/silcske/payload_internal.h file.
3892 * All include files that may be needed (public and some others
3893 included by the public headers) by application developers are
3894 now copied to the ./includes directory. It does not copy any
3895 internal headers. Affected file Makefile.defines.pre and all
3896 Makefile.am's under lib/ and subdirs.
3898 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Do not change the ~/.silc directory's permissions automatically.
3901 Affected file irssi/src/silc/core/clientutil.c.
3903 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3905 * Do not cancel the protocol in silc_server_close_connection
3906 it might cause recursion. Now cancelled in the function
3907 silc_server_free_sock_user_data. Affected file silcd/server.c.
3909 * Fixed the silc_server_remove_clients_by_server to regenerate
3910 the channel keys correctly finally. Added also new function
3911 silc_server_remove_clients_channels to actually do it.
3912 Affected file silcd/server.c.
3914 * Fixed the silc_server_new_channel to not crash by giving
3915 wrong router to the new channel. Affected file is
3916 silcd/packet_receive.c.
3918 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3920 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3921 which is given as argument to the silc_client_alloc now.
3922 It can be used to configure the client and set various parameters
3923 that affect the function of the client.
3925 * The USERS command in server did not check whether the channel
3926 is private or secret. Affected file silcd/command.c.
3928 * Added new argument to the USERS command in protocol specification.
3929 The USERS command now can take the channel name as argument
3930 as well. Added support for this in client and server and
3931 updated the protocol specs.
3933 * Completed the GETKEY command in client. It can be now used
3934 to fetch also servers public key not only some clients.
3935 Affected files lib/silcclient/command[_reply].c.
3937 * Added silc_client_get_server to return server entry by the
3938 server name. Affected files lib/silcclient/silcapi.h and
3941 * Redefined the IDENTIFY command in protocol specification to be
3942 more generic. It now can be used to query information about
3943 any entity in the SILC Network, including clients, servers and
3944 channels. The query may be based either the entity's name
3945 or the ID. Added support for this in both client and server.
3947 Affected files silcd/command.c and lib/silcclient/command.c
3948 and command_reply.c.
3950 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3951 the _from_client and _from_server functions. Affected file
3954 * Added silc_client_get_channel_by_id_resolve to the file
3955 lib/silcclient/silcapi.h to resolve channel information by
3956 its ID. Added also silc_client_get_channel_by_id that
3957 does not resolve it from the server.
3959 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3961 * Added SilcServerEntry context into the client library
3962 to represent one server. The INFO command now allocates
3963 these to save the resolved server info. For now on the
3964 client library will also keep information about servers,
3965 connected and resolved with INFO.
3967 The INFO command now allocates the SilcServerEntry context
3968 and saves the server info there. The COMMAND_REPLY in
3969 the INFO now returns the parameters to application in
3970 same order as defined in the protocol specification.
3972 The entries are cached in the client->server_cache.
3974 * The INFO command is now issued after received the Client ID
3975 from the server. Affected file lib/silcclient/client.c.
3977 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3978 to the application as the mode changer might be server.
3979 It is guaranteed that NULL is not returned anymore to the
3980 application. Affected file lib/silcclient/client_notify.c.
3982 The ID Type is now also passed to the application so that
3983 it can check whether the returned entry is SilcClientEntry
3986 Added new function silc_client_get_server_by_id to return
3987 the server entry by ID. Affected files are the
3988 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3990 * Do not create the channel in the Irssi SILC Client when issuing
3991 the JOIN command but when received the sucessful JOIN command
3992 reply. Otherwise the channel might get created even though we
3993 could not join it. The Affected file is
3994 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3996 * Fixed a channel joining bug in router. The router must also
3997 check the channel modes, invite and ban lists etc. when serving
3998 the JOIN command sent by normal server. Affected file is
3999 silcd/command.c. The router now resolves the client's
4000 information from the server who sent the JOIN command if it
4001 does not know it, and processes the JOIN command only after
4004 * Changed the SilcCommandCb to take new argument; void *context2.
4005 Affected file lib/silccore/silccommand.h
4007 The second argument in the command callbacks in the server now
4008 includes the SilcServerCommandReplyContext if the command was
4009 called as pending command callback from the command reply.
4010 Otherwise it is NULL. When called as pending the status of the
4011 command reply will be checked and if it was erronous the
4012 error will be sent to the original sender of the command.
4013 This way the client always receives the error messages even
4014 though the server was actually the one who received the error
4015 when it resent the command to router, for example. Affected
4016 files silcd/command[_reply].[ch].
4018 * Fixed sending WHOWAS command's error message to client if
4019 the requested client could not be found. It was missing.
4022 * Changed the CMODE and CUMODE commands reply arguments in the
4023 protocol specification. The Channel ID is now sent in both
4024 of the commands to identify the channel. Implemented this
4025 new feature to the client and server. Affected files
4026 lib/silcclient/command_reply.c and silcd/command.c.
4028 * Made better checks for invite and ban lists in the JOIN
4029 command in server. Affected file silcd/command.c.
4031 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4033 * The server now performs the incoming host IP/DNS lookup
4034 using the silc_socket_host_lookup and thus does not block
4035 the server anymore. Affected file silcd/server.c.
4037 * Completed the multi-thread support for SILC Scheduler in
4038 the lib/silcutil/silcschedule.c.
4040 * Fixed the configure.in.pre to detect the pthread correctly
4043 * Fixed a deadlock in silc_task_queue_wakeup in the file
4044 lib/silcutil/silctask.c.
4046 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4048 * Added new function silc_schedule_wakeup that is used in
4049 multi-threaded environment to wakeup the main thread's
4050 schduler. It needs to be used when a thread adds a new task
4051 or removes a task from task queues. After waking up, the
4052 scheduler will detect the task queue changes. If threads
4053 support is not compiled in this function has no effect.
4054 Implemented the wakeup mechanism to both Unix and WIN32
4055 systems. Affected files are lib/silcutil/silcschedule.[ch],
4056 lib/silcutil/unix/silcunixschedule.c and the
4057 lib/silcutil/win32/silcwin32schedule.c.
4059 * Added new function silc_task_queue_wakeup to wakeup the
4060 scheduler by the specified task queue. Affected file
4061 lib/silcutil/silctask.[ch].
4063 * The silc_socket_host_lookup_start now wakes up the scheduler
4064 after adding the timeout task. Affected file is
4065 lib/silcutil/silcsockconn.c.
4067 * The silc_socket_host_lookup is synchronous now if the threads
4068 support is not compiled in. However, the callback is still
4069 called asyncronously through the scheduler, anyway. Affected
4070 file lib/silcutil/silcsockconn.c.
4072 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4074 * Added new function silc_socket_host_lookup to perform
4075 asynchronous IP and FQDN lookups for the socket connection.
4076 Affected files lib/silcutil/silcsockconn.[ch].
4078 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4080 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4081 that may or may not compile the mutex support in.
4083 Changed the silc_mutex_alloc interface. It allocates the
4084 mutex now to the sent pointer and returns TRUE or FALSE.
4086 Affected file lib/silcutil/silcmutex.h.
4088 * Wrote the SILC Task Queue interface to support multi-threads.
4089 Affected file lib/silcutil/silctask.[ch].
4091 * Wrote the SILC Scheduler to support multi-threads. Affected
4092 file lib/silcutil/silcschedule.c.
4094 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4096 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4097 in lib/silcutil/win32/.
4099 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4101 * Defined SILC Mutex API and SILC Thread API and implemented
4102 them for Unix. Affected files are
4103 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4104 lib/silcutil/unix/silcunixmutex.c and
4105 lib/silcutil/unix/silcunixthread.c.
4107 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4109 * Fixed the silc_server_remove_clients_by_server's channel
4110 key re-generation. The hash table handling was incorrect
4111 and would not work with many channels. Affected file is
4114 * Fixed some memory leaks around the server code.
4116 * Rewrote the silc_server_get_users_on_channel to support IPv6
4117 based Client ID's. Affected file silcd/server.c.
4119 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4120 specification. However, a separate document must be written
4121 to define the detailed signing procedure and the payload
4122 associated with the flag. Defined the flag to the
4123 lib/silccore/silcchannel.h as well.
4125 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4127 * Changed the dynamic tables to static size tables in the
4128 lib/silccrypt/silchmac.c.
4130 * Removed GCC dependencies from the code. A patch by cras.
4132 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4134 * Do not show the error "Error receiving packet bla bla"
4135 in server if it really was not an error (-2 means that reading
4136 is pending). Affected file silcd/server.c.
4138 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4140 * Fixed a possible crash in silc_server_remove_clients_by_server
4141 in silcd/server.c. Fixed there also some memory leaks.
4143 * Fixed the silc_idlist_replace_client_id. It could replace
4144 wrong key in the hash table. Affected file silcd/idlist.c.
4146 * Do not check whether there are global users on the channel
4147 if the channel->global_users is FALSE. Affected functions
4148 silc_server_remove_from_one_channel and
4149 silc_server_remove_from_channels in silcd/server.c. Also,
4150 do not check if the removed client is local as we can be
4151 sure that global client was not removed from the channel
4152 and checking for global users is not needed.
4154 * The silc_server_remove_clients_by_server now re-generates
4155 the channel keys correctly for those channels that had
4156 clients removed from them. Affected file silcd/server.c.
4158 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4160 * Found the reason of random crashes in the server. We weren't
4161 ignoring the SIGPIPE signal (which can be sent in write())
4162 and it crashed the server. Affected file silcd/silcd.c.
4164 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4166 * Assure that sock->user_data is not NULL in the function
4167 silc_server_packet_send in silcd/packet_send.c.
4169 * Disconnect the remote connection if it could not be added
4170 to any ID lists in the server. The affected file is
4173 * Check in silc_server_packet_send[_real/dest] that the
4174 socket is not disconnecting and ignore the data if it is.
4175 Affected file silcd/packet_send.c.
4177 * Define inline to __inline on native WIN32 compilation.
4178 Affected file includes/silcwin32.h.
4180 * Added some explicit type casts for inline code since MSVC
4181 require them. Affected files lib/silcutil/silcbuffer.h,
4182 lib/trq/silcdlist.h and lib/trq/silclist.h.
4184 * Print warning in log files from now on if the packet
4185 decryption fails. Affected file silcd/server.c.
4187 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4189 * Changed the `say' client operation's interface to accept
4190 new `type' argument to indicate the type of the message sent
4191 by the library. The application may filter the library's
4192 messages according the type. The affected file is the
4193 lib/silcclient/silcapi.h.
4195 * Added two new functions to lib/silcclient/silcapi.h:
4196 silc_client_del_client and silc_client_del_client_by_id.
4197 Affected file lib/silcclient/idlist.c.
4199 * Moved the clientincludes.h from includes/ to silc/ and
4200 serverincludes.h from includes/ to silcd/.
4202 * The modes for the CMODE and CUMODE are now passed as
4203 uint32 for application with COMMAND_REPLY. The affected
4204 file is lib/silcclient/command_reply.c.
4206 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4208 * /WHOIS without arguments shows client's own information.
4209 Affected file lib/silcclient/command.c.
4211 * Changed PING to not accept any arguments. The specs
4212 says that client can ping only the connected server so
4213 requiring an argument is not needed. Affected file is
4214 lib/silcclient/command.c.
4216 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4218 * Fixed a fatal bug in private message sending and reception
4219 encryption and decryption when using private message keys.
4220 The implementation was incorrect and did not follow the
4221 specification. It causd that some of the message were
4222 lost since it did not use the sending and receiving keys
4223 as the protocol suggests. This has been fixed and will cause
4224 incompatibilities with older clients when sending private
4225 message encrypted with private message keys. Affected files
4226 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4227 and various other in Irssi SILC Client.
4229 Added `responder' boolean argument to the functions
4230 silc_client_add_private_message_key[_ske] to indicate when
4231 the key is added as responder or initiator of the key
4234 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4236 * Removed the silc_ske_check_version function and created
4237 a SilcSKECheckVersion callback. Added also a function
4238 silc_ske_set_callbacks that is now used to set all SKE
4239 callbacks. The callback functions are not given to
4240 the SKE functions anymore, but this function is used to
4243 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4245 * Added `silc_version' argument to the silc_client_alloc
4246 to define the version of the application for the library.
4247 The library will use the version string to compare it
4248 against the remote host's (usually a server) version
4249 string. Affected file lib/silcclient/silcapi.h
4251 * Added the KE protocol context to Key Agreement context
4252 in client library so that we can abort the SKE if it
4253 is in process when we get timeout. Affected file is
4254 lib/silcclient/client_keyagr.c.
4256 * Do not resolve the client ID forever if it returns in the
4257 first time that such client does not exist. This was done
4258 for example with private message. Affected file is
4259 lib/silcclient/client_prvmsg.c.
4261 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4263 * Do not add regex.h for WIN32. The affected file
4264 includes/silcincludes.h.
4266 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4267 not work yet 100%. It generates the DLL's automatically
4268 when compiling with --with-win32 under cygwin.
4270 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4272 * lib/contrib/regex.c is not compiled on WIN32.
4274 * Added silc_net_get_socket_opt function to the
4275 lib/silcutil/silcnet.h.
4277 * Added includes/silcwin32.h for WIN32 specific includes
4280 * Do not use ptime structure or any of the posix process
4281 functions on WIN32 in lib/silccrypt/silrng.c.
4283 * Added silc_gettimeofday to provide generic function
4284 for struct timeval on all platforms. Added the function
4285 to lib/silcutil/silcutil.h.
4287 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4289 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4290 library as they clearly belong there. As a plus side we
4291 can make the actual socket connection routines platform
4294 Added also new generic function silc_socket_read and
4295 silc_socket_write (that used to be silc_packet_[read/write].
4296 The implementation of these are platform specific.
4298 * Added WIN32 specific routines of silc_socket_[read/write]
4299 to lib/silcutil/win32/silcwin32sockconn.c.
4301 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4303 * Added preliminary support for native WIN32 compilation under
4304 cygwin (using the -mno-cygwin option for GCC) to the
4305 ./configure.in.pre. The --with-win32 now prepares the
4306 compilation for native WIN32.
4308 * Rewrote the SILC Scheduler interface in the file
4309 lib/silcutil/silcschedule.h. The scheduler is now context
4310 based and does not have anymore any global static scheduler.
4311 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4312 and created lib/silcutil/win32 directory for WIN32 based
4315 * Added Unix specific network routines to the
4316 lib/silcutil/unix/silcunixnet.c and the old
4317 lib/silcutil/silcnet.c includes now only generic routines.
4319 Added WIN32 specific network routines to the
4320 lib/silcutil/win32/silcwin32net.c.
4322 * Added Unix specific utility functions from the
4323 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4325 * Added WIN32 SILC Scheduler to the file
4326 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4329 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4331 * Do not handle JOIN notify in the server if the target client
4332 is not registered (idata->registered == FALSE). The affected
4333 file is silcd/packet_receive.c.
4335 * Update the nickrec->founder in event_cumode in the Irssi SILC
4336 client. Affected file irssi/src/silc/core/silc-channels.c.
4338 * Fixed the CUMODE_CHANGE notify handling in the server when
4339 server and router are announcing their clients on channels.
4340 Now the mode changes are saved and notified correctly. The
4341 affected file is /silcd/packet_receive.c.
4343 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4344 They really did not replace the cache entry in the ID Cache.
4345 Now they do that. Affected file silcd/idlist.c.
4347 * Fixed the KICK notify handling in the Irssi SILC client to
4348 update the channel records so that the kicked client does not
4349 appear to be on the channel. The affected file is
4350 irssi/src/silc/core/silc-channels.c.
4352 * Always update the conn->current_channel when executing command
4353 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4355 * Fixed the KILL notify handling in Irssi SILC client to remove
4356 the killed client on all channels.
4358 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Fixed the silc_parse_command_line to remove extra spaces
4361 from the start and end of the arguments. Affected file is
4362 lib/silcutil/silcutil.c.
4364 * Cancel and free any active protocol in the function
4365 silc_server_close_connection. Affected file silcd/server.c.
4367 * Cancel and free any active protocol in the function
4368 silc_client_close_connction. Affected file is
4369 lib/silcclient/client.c.
4371 * Do not execute the KILL command for clients that are in
4372 history (ie. they are not in the network). Affected file is
4375 * Fixed KILL notify handling, client does not crash anymore.
4376 Affected file irssi/src/silc/core/silc-channels.c.
4378 * Reduced the default packet buffer size from 2048 to 1024 in
4379 lib/silccore/silcpacket.c.
4381 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4382 counter to the SKE context that is incresed when the SKE library
4383 performs async operation outside the library. If the outside
4384 process frees the SKE context and FREED status will be set
4385 and the library will detect after the sync operation that the
4386 libary is freed. The affected files are
4387 lib/silcske/silcske[_status].[ch].
4389 * Resolve the client entry information in the function
4390 silc_client_channel_message to assure that NULL pointer is not
4391 passed as client entry to the application. */
4393 * Fixed the task timeout calculation to assure that there is
4394 never negative timeouts. The affected file is
4395 lib/silcutil/silcschedule.c.
4397 * Fixed the channel user mode notification sending in server.
4398 It was sent point-to-point to the router (or to server by router)
4399 but it needs to be destined to a channel. The routines now
4400 supports sending the channel user mode notifys to the channels
4401 when announcing clients and channels. Affected files are
4402 silcd/server.c and silcd/packet_receive.c.
4404 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4405 It did not actually replace the old channel entry in the cache.
4406 Affected file lib/silcclient/client_notify.c.
4408 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Fixed a possible crash in silc_packet_send_prepare. It now
4411 assures always that there is enough space in the buffer and
4412 at the tail area of the buffer (for MAC).
4414 Fixed the inbound buffer reallocation in silc_packet_read.
4415 It was old code and did not handle the reallocation correctly.
4418 The affected file is lib/silccore/silcpacket.c.
4420 * Fixed buffer overflow in silc_parse_nickname in the file
4421 lib/silcutil/silcutil.c.
4423 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * make install generates new server keys only if there is not
4428 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4431 Added check that if the NOREPLY is set then we will not send
4432 the away message. This avoids infinite loop of away messages
4433 if both clients are away. The affected file is
4434 lib/silcclient/client_prvmsg.c.
4436 * Fixed client crash if /NICK was given without arguments.
4437 Affected file lib/silcclient/command.c.
4439 * Server does not send the invite list in INVITE command back
4440 to the client if the list was not altered. Added this notion
4441 to the protocol spec as well. Affected file silcd/command.c.
4443 Fixed possible crash in INVITE command by checking the
4444 value of silc_server_get_client_route command.
4446 * Fixed the INVITE notify type handling. The arguments are now
4447 taken in correct order and client does not crash. The affected
4448 file is irssi/src/silc/core/silc-channels.c.
4450 Removed the "Inviting xxx to channel" message from the
4451 client library away and let the application handle it.
4452 Affected file lib/silcclient/command.c. Added that message
4453 to Irssi SILC client's message formats.
4455 * Fixed CMODE command crash in client. It now checks the
4456 amount of arguments correctly and does not crash. The affected
4457 file is lib/silcclient/command.c.
4459 * Do not create new channel automatically in silc_channels_join
4460 but check whether the channel by that name already exists.
4461 Affected file irssi/silc/core/silc-channels.c.
4463 * Do not send the SERVER_SIGNOFF to router if the disconnected
4464 entity was the router. Affected file silcd/server.c.
4466 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4467 SILC client as it was missing from there.
4469 Added the handling of the KICK notify to the Irssi SILC client
4470 as it was missing. Added "you have been kicked" message to
4471 Irssi SILC client's message modules formats.
4473 Added the handing of the KILL notify to the Irssi SILC client
4474 as it was missing. Added the kill message module formats
4477 The affected file is irssi/src/silc/core/silc-channels.c.
4479 * The router did not save the channel mode the server announced.
4480 Affected file silcd/packet_receive.c.
4482 * Fixed a possible crash in INFO command in server. If the
4483 server did not provide the server info it crashed. Affected
4484 file silcd/command.c.
4486 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4488 * Fixed the GETKEY command in the server to check also the
4489 global list. Otherwise the GETKEY would not work correctly
4490 in normal SILC server. Affected file silcd/command.c.
4492 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Fixed GETKEY crash, it crashed if the command did not succseed.
4496 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4499 is now real and not just an macro interface to GMP.
4501 Removed the entire GMP from the source tree and imported new
4502 NSS MPI library instead. Reason for removing GMP is that it is
4503 extremely large and compiles extremely slow. The NSS MPI
4504 is only a few files and compiles in less than 10 seconds.
4505 The speed is also about the same as GMP. The MPI is imported
4506 to lib/silcmath/mpi.
4508 If the system has GMP installed we will still use the GMP.
4509 If it is not then the NSS MPI will be compiled.
4511 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Merged a long nickname (127 characters long) crash bugfix from
4514 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4516 * Merged a freed memory reference bugfix from Irssi CVS tree.
4517 Affected file irssi/src/core/commands.c.
4519 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Added the server's public key sving and verification to the
4522 server when performing the SKE. This was missing and the
4523 remote server's (or router's) public key was accepted without
4524 checking whether we have it previously or trust it at all.
4525 Affected file silcd/protocol.c.
4527 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Check in the silc_server_timeout_remote if protocol is active
4530 and make sure that the protocol's final callback is called so
4531 that all memory if freed. Affected file silcd/server.c.
4533 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4535 * silc_server_whois_send_reply crashed the server if the nickname
4536 was 127 characters long. Affected file silcd/command.c.
4538 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * Added sanity check to the silc_server_new_client. If the hostname
4541 is provided inside username then check that the provided hostname
4542 really is the same as the resolved one. If the hostname was not
4543 resolved then check it from the public key. Affected file is
4544 silcd/packet_receive.c.
4546 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4547 if the server disconnected us and the connection is not valid
4548 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4550 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4551 the library to the lib/silcutil/silcutil.[ch].
4553 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Close log file after open. Affected file
4556 lib/silcutil/silclog.c.
4558 * Check whether sock == NULL in silc_client_send_packet and return
4559 if it is. Affected file lib/silcclient/silcclient.c.
4561 * Check rec->entry == NULL in the Irssi SILC Client before
4562 sending the channel message. Affecte file is
4563 irssi/src/silc/core/silc-servers.c.
4565 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Merged a splitted window bugfix from Irssi CVS tree. The
4568 affected file is irssi/src/fe-text/textbuffer-view.c.
4570 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4571 It did not print nickname.
4573 * Improved the distributions system a bit.
4575 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4578 irssi/src/fe-text/gui-window.c.
4580 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4581 to in-active server. The affected file is
4582 irssi/src/silc/core/client_ops.c.
4584 * Resolve the client in USERS command reply if the entry does
4585 not have username resolved. The affected file is
4586 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4587 command to WHOIS command to really resolve stuff. The USERS
4588 is not used any more in any critical section so WHOIS can
4589 be used even though it might be slower than IDENTIFY.
4591 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4594 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Changed the protocol API a bit more consistent in the
4597 lib/silccore/silcprotocol.[ch].
4599 * Changed the following headers to ROBODoc format:
4601 lib/silccore/silcpayload.h
4602 lib/silccore/silcprotocol.h
4603 lib/silccore/silcsockconn.h
4605 All core library headers are now formatted.
4607 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Fixed a bug in Irssi SILC client; do not show that you are
4610 server/router operator if you really are not. Affected file is
4611 irssi/src/silc/core/client_ops.c.
4613 * Renamed silc_command_free_payload to silc_command_payload_free.
4614 Affected file lib/silccore/silccommand.h
4616 * Added silcmath.h to include the prototoypes of various routines
4617 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4620 * Changed the following headers to ROBODoc format:
4622 lib/silccore/silcchannel.h
4623 lib/silccore/silccommand.h
4624 lib/silccore/silcid.h
4625 lib/silccore/silcidcache.h
4626 lib/silccore/silcmode.h
4627 lib/silccore/silcnotify.h
4628 lib/silccore/silcpacket.h
4629 lib/silcmath/silcmath.h
4631 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Added checking to the server code not to start the server if
4634 ciphers and stuff are not configured properly. Affected files
4635 silcd/serverconfig.[h] and silcd/server.c.
4637 * Changed the layout of the header files of the public interfaces
4638 in the SILC libraries. The new layout supports ROBODoc
4639 documentation tool (and some others) so that it is easy to create
4640 a library reference manual. All the other headers and source
4641 code must still follow the CodingStyle document. Also source
4642 code must not include these ROBODoc stuffs, only the headers.
4643 Furthermore, all public interface headers must now be named
4644 by using `silc' prefix, example: silcapi.h, silccipher.h.
4645 Some files were renamed due to this. All the other headers
4646 must not be used as public interfaces. I will update the
4647 CodingStyle document later. Changed following headers, so far:
4649 lib/silcclient/silcapi.h
4650 lib/silccore/silcauth.h
4651 lib/silccore/silcprivate.h
4652 lib/silccrypt/silcdh.h
4654 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Removed silc_client_packet_send_flush from the client library
4659 as it is not needed. Affected file lib/silcclient/client.[ch].
4661 * Added printing of message of unresolved authentication method
4662 to the Irssi SILC client. Added it to the module formats.
4663 Removed the same message from the client library.
4665 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Added new distribution feature, DISTLABEL. Every distribution
4668 can define own preprocessor label that can be used in the
4669 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4670 file distributions, acconfig.h.pre and prepare.
4672 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Added Makefile.defines_int to include the actual definitions
4675 for Makefile.defines.in. Tested the new distribution system,
4676 created distributions and tested installation.
4678 * Added AWAY message printing to the Irssi SILC client. Added
4679 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4681 * Added SCONNECT command to call the SILC's CONNECT command.
4682 Cannot use CONNECT directly since Irssi uses that internally.
4683 Affected file irssi/src/silc/core/silc-servers.c.
4685 Added ACTION local command. It is same as ME command but takes
4686 the channel as mandatory argument.
4688 Rewrote some of the Irssi's help files to suite for SILC
4691 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Added Makefile.defines[.in] that should for now on be included
4694 in all Makefile.am file in the source tree. That file includes
4695 all common compilation definitions for SILC source tree.
4697 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Minor changes to the ./prepare script to change the package
4700 name according the distribution name to the configure.in.
4702 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Created new distribution system. Added file `distributions'
4705 that defines all the distributions that can be created out of
4706 the SILC source tree. The ./prepare script now reads that
4707 file to determine how to prepare the distributions. The
4708 first argument to the ./prepare is the name of the distribution
4709 and second is the version of the distribution. If given
4710 without arguments it creates the default (toolkit) distribution
4711 with the default version (defined in ./prepare).
4713 All Makefile.am files that are subject to the distributions
4714 are now named as Makefile.am.pre. These are ./Makefile.am
4715 and lib/Makefile.am. Others may be changed later.
4717 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Added invite list, ban list, some key management and connection
4720 error message printing to module formats in the Irssi SILC client.
4722 * Added new silc_client_set_away_message to set the away message
4723 that is back to the person who sent private message. The
4724 affected file lib/silcclient/silcapi.h and the
4725 lib/silcclient/client_prvmsg.c.
4727 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Fixed the private message sending in the Irssi SILC client,
4730 added local command KEY to the Irssi SILC client.
4732 Added key management and key agreement message formats to the
4733 irssi/src/fe-common/silc/module-formats.[ch].
4735 Added USERS (alias WHO) printing, server/router operator
4736 indication and LIST command printing to the module formats.
4738 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Fixed channel joining notify handling, cumode notify handling
4741 from Irssi SILC client.
4743 * Added SILC specific module-formats to the Irssi SILC client so
4744 that SILC specific message hilighting, colors etc is possible.
4745 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4747 Added channel mode, channel user mode, actions, notices,
4748 whois and whowas printing to the the module-formats.c.
4750 * Fixed a bug in channel deletion in the server. The channel
4751 is not left to the cache even if the channel founder auth mode
4752 is set when there are no users anymore on the channel. Affected
4753 file silcd/server.c.
4755 * The silc_net_localhost now resolves the entire hostname including
4756 the domain name. Affected file lib/silcutil/silcnet.c.
4758 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Changed the ask_passphrase client operation to be ascynchronous.
4761 It has now a completion callback and a context that the
4762 application must call after it has got the passphrase from
4763 the user. Affected files lib/silcclient/silcapi.h,
4764 lib/silcclient/protocol.c, lib/silcclient/command.c and
4767 Added SilcAskPassphrase callback that the application calls
4768 to deliver the passphrase to the library.
4770 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4771 The public key verification and especially a certificate
4772 verification is asynchronous procedure.
4774 Added new SILC_SKE_STATUS_PENDING status to indicate the
4775 request is pending and a callback will be called to finalize
4778 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4779 indicate that remote end did not send its public key (or
4780 certificate), even though we require it. Added check for this
4781 condition in the SKE. This was a security bug, now fixed.
4783 Defined new SilcSKEVerifyCbCompletion callback that is called
4784 when the verification process is completed.
4786 The affected files lib/silcske/silcske_status.h and
4787 lib/silcske/silcske.[ch].
4789 * Changed the verify_public_key client operation to be async
4790 as well. Defined SilcVerifyPublicKey callback that is used to
4791 indicate the success of the public key verification process.
4793 Changed the server and client to use the new async client
4796 * Changed the Irssi SILC client's internal scheduler to be called
4797 twice as many times as it used to be. As a result the client
4798 should be a bit faster now. Affected file is
4799 irssi/src/silc/core/silc-core.c.
4801 * Added support to Irssi SILC client of asynchronous public key
4802 verification and passphrase inquiry. Affected file is
4803 irssi/src/silc/core/silc-core.c.
4805 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Do not say "You have left channel %s" in client library.
4808 Moved it to the application. Affected files are
4809 lib/silcclient/command.c and silc/client_ops.c.
4811 * Fixed silc_client_get_clients. Command context was not
4812 duplicated and was freed memory in the callback. Affected
4813 file lib/silcclient/idlist.c.
4815 * Do not say "you are now talking..." on JOIN command in the
4816 client library. The appliation must handle it.
4818 * Do not say ".. changed topic to" in command reply in the
4819 client libary. The application must handle it.
4821 * Fixed TOPIC command sending in the client library.
4823 * Fixed a memory leak in silc_client_command_free in the file
4824 lib/silcclient/command.c.
4826 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Imported a modified version of Irssi client to the source tree.
4829 The Irssi will be used to create a new client called
4830 Irssi SILC. Imported to irssi/.
4832 Added silc_core_init_finish function to the Irssi. Affected
4833 file irssi/configure.in.
4835 A lot changes in the Makefile.ams around the irssi tree.
4837 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Do not rehash if the new size is same as the old size of the
4840 hash table, in the silc_hash_table_rehash*. The affected file
4841 lib/silcutil/silchashtable.c.
4843 * Replaced hash_table_del_by_context calls from the server
4844 (when channel->user_list and client->channels) to the
4845 hash_table_del as it is sufficient and faster.
4847 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Added silc_hash_table_list, silc_hash_table_get and the
4850 SilcHashTableList structure to provide an alternative way to
4851 traverse the hash table. The affected files are
4852 lib/silcutil/silchashtable.[ch].
4854 * Changed the server's idlist routines to use the hash table
4855 routines to optimize the code.
4857 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Replaced the client entry's `channel' list and channel entry's
4860 `user_list' list to hash tables for optimized lookup. Changed
4861 the code to use the hash table interface around the code.
4862 Affected file lib/silcd/idlist.[ch].
4864 * Added `auto_rehash' boolean argument to the function
4865 silc_hash_table_alloc to indicate whether the hash table should
4866 auto-rehash when it thinks is appropriate time. It will
4867 increase the hash table size if the there is twice as much
4868 entries in the table than the size of the table, and will
4869 decrease the size if there are twice as less entries than
4870 the size of the table.
4872 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4876 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * silc_idcache_purge_by_context deletes the entry now by context
4879 as it is supposed to do. Affected file lib/silccore/idcache.c.
4881 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4882 client is not anymore valid (WHOWAS givens the info) and not
4883 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4885 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Removed the `data' and `data_len' arguments from the ID Cache
4888 interfaces and added `name' argument. ID Cache does not handle
4889 anymore the binary data only a names associated with given ID.
4891 * When hashing a Client ID with silc_hash_id the entire ID is
4892 not hashed anymore, instead only the hash of the Client ID is
4893 hashed. This way we can access the Client ID from the cache
4894 with Client ID but with the hash of the ID (which is a hash of
4895 the nickname) as well without any difference in performance.
4897 Added also silc_idcache_find_by_id_one_ext to do one on one
4898 searching when we have the actual ID. Added also function
4899 silc_hash_client_id_compare. The affected files are
4900 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4902 * When hashing the name associated with a ID it is always done
4903 in lowercase. This way we can access the cache without worrying
4904 about case-sensitivity, even though, for example nicknames are
4907 * Fixed a bug in server with channel message sending. It put
4908 wrong ID type as destination ID. The affected file
4909 silcd/packet_send.c.
4911 * silc_idcache_del_by_context now deletes from all hash tables
4912 by context. Affected file lib/silccore/idcache.c.
4914 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Changed the client library to use the new ID Cache interface.
4917 Changes around the source tree.
4919 * Added silc_hash_table_rehash_ext to rehash with specific
4920 hash function. Affected file lib/silcutil/silchashtable.[ch].
4922 * Added silc_hash_string_compare to compare two strings in the
4923 hash table. Affected file lib/silcutil/silcutil.[ch].
4925 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Added new function silc_idcache_del_by_context into the
4928 lib/silccore/idcache.[ch].
4930 * Changed the server's ID list routines to use the new ID Cache
4931 interface. Changes around the source tree.
4933 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added silc_hash_table_del[_by_context]_ext functions in to the
4936 lib/silcutil/silchashtable.[ch].
4938 Removed silc_hash_table_find_all* routines and added new
4939 silc_hash_table_find_foreach to replace them.
4941 Added silc_hash_table_replace_ext function as extended
4942 replacing function. Separated the simple hash table interface
4943 from the extended hash table interface in the file
4944 lib/silcutil/silchashtable.h.
4946 * Fixed minor bugs and changed it to use some of the new
4947 hash table functions in lib/silccore/idcache.c
4949 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4951 * Added new function silc_hash_table_find_all to return all keys
4952 in the hash table by the specified key. As the hash table is
4953 collision resistant it also makes it possible to have several
4954 duplicate keys in the hash table. This function may be used to
4955 find all of the keys from the hash.
4957 Added user_context arguments to the SilcHashFunction,
4958 SilcHashCompare and SilcHashDestructor to deliver user specified
4961 Added new fuctions silc_hash_table_find[_all]_ext to do
4962 extended lookup with specified hash and compare functions and
4963 specified user contexts.
4965 Added new function silc_hash_table_add_ext to add the key
4966 with specified hash function and user context.
4968 Added new function silc_hash_table_foreach to traverse all
4969 entrys in the hash table. Added SilcHashForeach callback
4972 Added new function silc_hash_table_del_by_context to delete
4973 the entry only if the context associated with the key matches.
4975 Affected files are lib/silcutil/silchashtable.[ch].
4977 * Removed silc_hash_[server/client/channel]_id and added just
4978 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4979 silc_hash_id_compare to compare two ID's using as the hash table
4980 comparison function. Added also silc_hash_data to hash
4981 binary data and silc_hash_data_compare to compare it.
4983 * Removed silc_idlist_find_client_by_hash as it is not needed
4984 anymore. Affected file silcd/idlist.[ch].
4986 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4987 to use internally the SilcHashTable. The new ID Cache is a lot
4988 faster than the old one. Some of the ID Cache interface was also
4989 rewritten and obsolete and stupid functions were removed.
4991 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Added entry_count field to the SilcHashTable to keep the number
4994 of the entries in the table. Implemented the function
4995 silc_hash_table_rehash. Added new function
4996 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4998 Fixed a minor bug in silc_hash_table_free.
5000 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5001 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5002 into the lib/silcutil/silcutil.[ch].
5004 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Implemented a collision resistant hash table into the
5007 lib/silcutil/silchashtable[ch]. See the header and the source
5008 for the SilcHashTable API.
5010 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Merged dotconf version 1.0.2 into lib/dotconf.
5014 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Do not compile anything in lib/silcsim/* if the SIM support
5017 is not enabled. The tree should now compile without problems
5020 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Compiled the SILC under cygwin. Compiled and tested briefly
5023 without problems. More tests needed. The SIMs didn't compile
5026 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5028 * Fixed possible crash in silc_get_username in the
5029 lib/silcutil/silcutil.c.
5031 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Fixed a va_arg in silc/client_ops.c.
5035 * Oops, RC5 routines were named AES and caused some problems
5036 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5038 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Added new SilcIDIP structure into the lib/silccore/id.h and
5041 replaced the old `ip' fields from all SILC ID's to that type.
5042 This is a step towards IPv6 support.
5044 The silc_id_get_len takes now the ID as an extra argument.
5045 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5046 both IPv4 and IPv6 based ID's.
5048 The affected files are lib/silccore/id.[ch] and other files
5049 around the tree using these routines.
5051 * Removed the ID length arguments in server from various
5052 silc_server_send_notify_* routines -> they are not needed
5055 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Fixed memory leak in silc_encode_pem_file in the file
5058 lib/silcutil/silcutil.c.
5060 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Check minor version as well in the SKE. Affected files are
5063 silcd/protocol.c and lib/silcclient/protocol.c.
5065 * Added --identifier option to the server so that an identifier
5066 can be when creating the public key for the server. Affected
5067 file is silcd/silcd.c.
5069 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5070 lib/silccrypt/silcpkcs.c.
5072 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Register default ciphers and stuff when using -C option with
5075 the server. Affected file sildc/silcd.c.
5077 * Put back the servers public key filename format, it is better
5078 than the new one. For now, the client keys are saved with the
5079 new filename format. The affected file silc/client_ops.c.
5081 * Implemented the Cipher API for the rest of the ciphers that
5082 did not implement it or implemented it the wrong way.
5084 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Register default ciphers and stuff when using the -S option
5087 in the client. Affected file silc/silc.c. Same also when
5088 creating new key pair with -C option.
5090 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Fixed the silc_verify_public_key client operation function to
5093 save the public keys differently. The fingerprint is now
5094 used as filename and not the hostname. This way also the
5095 client keys are saved uniquely and not with hostnames. The
5096 affected file is silc/client_ops.c.
5098 * Trimmed the silc_hash_fingerprint function to remove extra
5099 whitespaces from the end of the fingerprint. The affected
5100 file is lib/silccrypt/silchash.c.
5104 * Added silc_cipher_register_default function to register all
5105 default ciphers. It can be used when configuration files
5106 does not exist and the application does not want any specific
5107 ciphers in any specific order.
5109 The SilcDList is now used as silc_cipher_list dynamically
5110 allocated cipher list. Removed the static list all together
5111 and now all ciphers must be allocated to the dynamic list.
5112 The silc_cipher_alloc routine was changed to check only the
5115 All silc_cipher_* routines that used to return int returns
5118 The affected files lib/silccrypt/silccrypt.[ch].
5120 * The same thing was done to silc_hash_* as for silc_cipher_*
5121 routines. Affected files lib/silccrypt/silchash.[ch].
5123 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5124 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5125 Added also silc_pkcs_[un]register[_default] functions.
5126 Removed the data_context from the PKCS API.
5128 * Added silc_hmac_register_default function to register default
5129 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5130 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5131 to unregister all hmacs at once.
5133 * Register the default ciphers, hash functions, PKCSs and HMACs
5134 if client's configuration file does not exist. The affected
5137 * The client did not load the hash functions from the SIM
5138 modules at all. Added support for this. Affected file is
5139 silc/clientconfig.c.
5141 * When decoding public key with silc_pkcs_public_key_decode, check
5142 the supported algorithm only if PKCS are registered. Affected
5143 file lib/silccrypt/silcpkcs.c. The same was done with the
5144 silc_pkcs_private_key_decode.
5146 * Fixed the SILC List routines to keep the list always in order.
5147 It used to change the list's order when traversing the list but
5148 not it preserves the order. Affected file lib/trq/silclist.h.
5150 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Added the client library to use the SilcSocketConnection's
5153 reference counter (by silc_socket_dup) to prevent the bug that
5154 the socket object may be freed underneath async operation.
5156 * The name resolv library checking fixes in the configure.in.pre.
5159 * Created new version of the protocol drafts for future
5160 development. The -03 drafts are the ones that will be changed
5161 in the trunk now and the -02 will remain as they are.
5163 * Send list of CUMODE notifys to the router when announcing
5164 the channel users to the router. Affected file silcd/server.c.
5165 If the router receiving channel founder CUMODE for a channel
5166 that already has channel founder it will send CUMODE notify
5167 to the sender to remove the channel founder rights from the
5168 announced client. Affected file silcd/packet_receive.c.
5170 * The CUMODE notify may now use Server ID as well as the entity
5171 who changes the mode. Updated protocool specs.
5173 * Updated INSTALL and README files.
5175 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * New web pages in the http://silc.pspt.fi. The pages was
5182 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Implemented the [DenyConnectin] config section in the server.
5185 Added silc_server_config_denied_conn to check whether incoming
5186 connection is denied. Affected file silcd/serverconfig.[ch].
5188 * Do not check the ports when checking the incoming configuration
5189 data if the port is 0, meaning any. Affected file is
5190 silcd/serverconfig.c.
5192 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5194 * Fixed buffer overflow in silc_string_compare in the file
5195 lib/silcutil/silcutil.c.
5197 * Fixed double free in silc_server_command_leave in the file
5200 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Fixed the version checking in the server. Affected file is
5205 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Fixed the configuration data fetching when accepting new
5208 connections in the server. Affected file silcd/server.c.
5210 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Added `sender_entry' argument to the function
5213 silc_server_packet_relay_to_channel so that we can check
5214 whether some destination actually belongs to the same route
5215 the sender belongs (ie, we must not resend the packet to the
5216 sender). Affected file silcd/packet_send.[ch].
5218 * Added `servername' field to the SilcClientEntry in the server
5219 to hold the name of the server where client is from. Affected
5220 file is silcd/idlist.h.
5222 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Moved the channel message encrypting in the router betwen
5225 router connections from silc_server_channel_message to the
5226 silc_server_packet_relay_to_channel since we want to check
5227 whether we have anybody channel before encrypting anything.
5228 Affected files silcd/packet_[receive/send].c.
5230 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Fixed the [AdminConnection] server config section to support
5233 multiple entries. Affected file silcd/serverconfig.c.
5235 * Added support into the server to check the validity of the
5236 incoming connection before executing any KE or authentication
5239 * The connection configuration is now saved to the KE and
5240 connection auth protocol contexts and not fetched anymore in
5241 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5243 * The local hosts listenning address and port is also resolved
5244 now when starting the server. We want to have the socket object
5245 to include the real address and port for the listener. Added
5246 new function silc_net_check_local_by_sock into the files
5247 lib/silcutil/silcnet.[ch].
5249 * Fixed a broadcast bug in server -> do not broadcast if we
5252 * Fixed a routing bug. Do not route broadcast packets ever.
5253 Broadcast packets must be processed always and not routed since
5254 they may be destined to some other host than yourself and thus
5255 would get routed without no good reason. Affected file is
5258 * Added function silc_server_config_is_primary_route to check
5259 whether primary router connection has been configured (a router
5260 configuration that we are initiating). If there is not, we
5261 will assume that there is only two routers in the SILC network
5262 and we will use the incoming router connection as our primary
5263 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5265 * Changed the order of the broadcasting. Broadcast _after_ the
5266 packet has been processed not before. Affected file is
5269 * Fixed a [ClientConnection] parsing bug. The port was never
5270 parsed correctly thus resulting to port 0. Affected file
5271 silcd/serverconfig.c.
5273 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5274 argument and did not set the broadcast packet flag. Affected
5275 file silcd/packet_send.c. Fixed same bug in the function
5276 silc_server_send_notify as well.
5278 * If we receive NEW_ID packet for our own ID in the server, ignore
5281 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Removed the nickname from the Private Message Payload.
5286 Updated the code and the protocol specs.
5288 * Updated protocol specs for submitting to the IETF.
5290 * Tweaked the Random Number Generator a bit. Affected file
5291 lib/silccrypt/silcrng.c. Exported a new function
5292 silc_rng_[global]_add_noise which can be used to add more
5295 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Do not parse packets with different timeout when protocol
5298 is active -> may cause problem with rekey. Affected file
5301 * When server receives signoff notify it must not create
5302 new channel key if the client is on any channels since the
5303 sender of the signoff notify will create it.
5305 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Added printing of error messages during SKE protocol from the
5308 failure packet sent by server during SKE. Affected file
5311 * Removed the client's failure_callback handling with timeout
5312 and handle it immediately when received.
5314 * The SKE library returned wrong type in SUCCESS and FAILURE
5315 packets. They must be 32 bit MSB not 16 bit MSB.
5317 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Ok, rewrote the logic of the re-key and now it seems to work.
5320 I tested it on high traffic with frequent re-keys without
5321 problems. Added hmac_receive (and renamed hmac to hmac_send)
5322 in SilcClientConnection in lib/silcclient/client.h and
5323 in SilcIDListData in silcd/idlist.h. Also, removed the
5324 SilcPacketParserContext's cipher and hmac fields as they are
5325 not needed anymore and actually caused some problems when
5326 the ciphers and hmac's changed underneath the packet parser.
5328 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5330 * If re-key protocol is active then process the incoming packets
5331 synchronously since we must assure that icoming packets encrypted
5332 with the old key is processed before the new keys is set to
5333 use. This is true other packets than for REKEY packets.
5334 Affected file silcd/server.c. The same was done to client library
5335 as well, affected file lib/silcclient/client.c.
5337 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Fixed bug in client and server to accept the force send if
5340 the packet is send from silc_[server/client]_packet_process
5341 function. Otherwise the packets are never delivered, oops.
5343 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Disable force sending of packets when REKEY protocol is active.
5346 We must assure that no packet is sent directly when rekey is
5347 performed. All packets must be sent through packet queue.
5348 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5349 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5350 function is silc_[server/client]_packet_send_real to check
5353 * Replaced the SIM paths from example config files to
5354 /usr/local/modules. Also, make install creates now
5355 /usr/local/silc/logs directory to hold all the SILC server
5358 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Made the configure.in.pre work on Solaris. Patch by salo.
5362 * Made all ciphers compatible with non-x86 machines. Defined
5363 CBC mode macros into lib/silccrypt/ciphers_def.h.
5365 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5367 * Fixed the make install.
5369 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * When MAC computation fails the silc_packet_decrypt returned 0
5372 even though it was supposed to return -1. Fixed this. The
5373 affected file is lib/silccore/silcpacket.c.
5375 * Do not replace the config files in /etc/silc (in make install)
5376 if they already exist. Affected file ./Makefile.am.
5378 * Do not send re-key packets immediately but through packet queue.
5379 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5381 * Changed silc_net_check_host_by_sock to return FALSE if the
5382 IP/DNS could not be resolved. Though, it returns the IP address
5383 now even if it could not resolve it (but returns also FALSE).
5384 Affected file lib/silcutil/silcnet.[ch].
5386 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Added silc_pkcs_decode_identifier to decode the public key's
5389 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5390 Added also silc_pkcs_free_identifier. Added also new context
5391 SilcPublicKeyIdentifier.
5393 * Added -S option to the silc client. It is used to dump the
5394 contents of the specified public key file.
5396 * Changed the PKCS api to return the public key length when
5397 setting the public key.
5399 * Fixed a fatal bug in the public and private key file loading.
5400 Affected file lib/silccrypt/silcpkcs.c.
5402 * Execute the packet parsing for client with zero (0) timeout
5403 if the protocol is active. Affected file silcd/server.c.
5405 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Made the key generation options to the silcd program. Added
5408 -C option, equivalent to client's option.
5410 * Added new [ServerKeys] config section to the server. It
5411 configures the server's public and private key.
5413 * Defined generic Public Key Payload into the protocol
5414 specification to send specific type of public keys and
5417 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5418 public key or certificate.
5420 * Implemented the GETKEY command to the server and to the
5421 client library and on user interface.
5423 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Made preliminary `make install' work.
5427 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Added SilcServerRekey context into silcd/idlist.h.
5431 * Added the PFS support as defined in the specification to the
5432 SKE protocol. Affected files lib/silcske/*.c.
5434 * Added `ske_group' field to the SilcServerRekey context to hold
5435 the number of the SKE group that is used with PFS in re-key.
5436 Affected file silcd/idlist.h.
5438 * Added PFS re-key support to the server. Affected file is
5441 * Added silc_protocol_cancel to cancel execution of the next
5442 state of the protocol. Affected file is
5443 lib/silccore/silcprotocol.[ch].
5445 * Added the re-key support with and without PFS to the client
5446 library. Re-key is performed once in an hour, by default.
5448 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5449 Added silc_client_rekey_callback and silc_client_rekey_final.
5450 Affected files are lib/silcclient/protocol.[ch] and
5451 lib/silcclient/client.[ch].
5453 * Removed the `hmac_key' and `hmac_key_len' fields from the
5454 SilcClientConnection structure; not needed. Affected file is
5455 lib/silcclient/client.h.
5459 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Do not ask whether user wants to use the negotiated private key
5462 for private messages, just use it. Affected file is
5463 silc/local_command.c.
5465 * Added `send_enc_key' and `enc_key_len' fields to the
5466 SilcIDListData structure since they are needed in the re-key
5467 phase. Affected file is silcd/idlist.[ch].
5469 * Implemented the simple re-key protocol into the server.
5470 Affected files silcd/server.c and silcd/protocol.[ch]. The
5471 re-key will be performed once in an hour, by default.
5473 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5474 Added silc_server_rekey, silc_server_rekey_callback and
5475 silc_server_rekey_final.
5477 * Removed Tunneled flag from the protocol. Updated the code
5478 and the specifications.
5480 * Adde `pfs' field to the SilcIDListData to indicate whether
5481 the PFS is to be performed in the re-key. Affected file is
5484 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5487 int64 of at least the xintXX size. If void * is less that 4
5488 bytes uint32 * will be used. Defined bool as boolean.
5490 * Changed _ALL_ unsigned long and unsigned int to uint32,
5491 unsgined short to uint16 in the source tree.
5493 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5494 not handle clients that has entry->data.registered == FALSE.
5495 They are not in the network anymore. Affected file is
5498 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Implemented the sending of the SERVER_SIGNOFF notify in the
5501 server. Affected file is silcd/server.c.
5503 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5504 Added also silc_notify_payload_encode_args into the
5505 lib/silccore/silcnotify.[ch].
5507 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5508 Affected file silcd/packet_receive.c.
5510 * Implemented the SERVER_SIGNOFF notify handling in the client
5511 library. Affected file lib/silcclient/client_notify.c. Also,
5512 implemnted the printing of the SERVER_SIGNOFF info to the
5513 application. Affected file silc/client_ops.c.
5515 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5516 if the deleting was successful. Affected file silcd/idlist.[ch].
5518 * Added support for public key authentication in the connection
5519 authentication protocol in the client library. Affected file
5520 lib/silcclient/protocol.c.
5522 * Changed the server's silc_idlist_get_clients_by_* interface
5523 to support already allocated array so that new entries may be
5524 added to pre-allocated array. Affected file silcd/idlist.[ch].
5525 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5526 and command replies.
5528 * All command reply functions in the server now calls the
5529 pending command callback even if error occured. This way the
5530 error will be delivered to the client as well. Affected files
5531 silcd/command.c and silcd/command_reply.c.
5533 * Fixed INFO command to return local server's info if no server
5534 was provided. Affected file lib/silcclient/command.c.
5536 * Removed RESTART command for good. Updated the code and the
5539 * Rewrote parts of the task system. It is a bit simpler now.
5540 Removed unsued task priorities. The affected files are
5541 lib/silcutil/silctask.[ch].
5543 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Moved the USERS printing from the library to the application.
5546 Affected files lib/silcclient/command.c and silc/client_ops.c.
5548 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * Added channel key re-key support. The re-key is perfomed
5553 only by the router and is done once in an hour. Added `rekey'
5554 field to the SilcChannelEntry in the server. Affected files
5555 silcd/server.c and silcd/idlist.h.
5557 * Added silc_task_unregister_by_context into the file
5558 lib/silcutil/silctask.[ch].
5560 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Added SILC_UMODE_GONE mode to indicate when the client is not
5563 present in the SILC network. Added also support to the local
5564 command AWAY that will set this mode. Added support of showing
5565 "xxx is gone" in WHOIS command. The USERS command shows the
5566 gone status as well.
5568 * Fixed setting server and router operator privileges in the
5569 server's UMODE command. Affected file silcd/command.c.
5571 * Merged the SKE KE1 and KE2 payloads into one payload. The
5572 new KE payload is equivalent to the old KE2 payload.
5574 Cleaned up the SKE Start Payload parsing. It now uses the
5575 simple buffer unformatting to do the parsing. A lot faster
5578 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5579 to the SKE that is used to indicate whether both of the SKE
5580 parties should perform authentication. By default only the
5581 responder performs authentication. By setting this flag also
5582 the initiator must do authentication. By default it is unset
5583 since in normal SKE case, client to server connection, only
5584 the responder should do authentication. When doing SKE between
5585 two clients both should perform authentication. Updated the
5586 code and the protocol specs.
5588 * A little fix to IDENTIFY command in the server. Search the
5589 client first by hash not nickname. Affected file is
5592 * Fixed the silc_client_close_connection to support closing
5593 the client to client connections wihtout deleting too much
5594 data. Affected file lib/silcclient/client.c.
5596 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5597 are received if protocol used to be active but is not anymore
5598 the application would crash due to NULL pointer dereference.
5599 Affected files silcd/server.c and lib/silcclient/client.c.
5601 * Added `hash' field to the SilcClientConnection to include
5602 the hash function negotiated in the SKE protocol.
5604 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5605 to set the channel founder authentication data. A client can
5606 claim the founder rights later by providing the authentication
5607 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5608 This way the channel founder can regain the channel founder
5609 privileges even it is left the channel. This works only on
5610 local server and the client must be connected to the same
5611 server to be able to regain the founder rights. Updated the
5612 protocol specs accordingly.
5614 Added support to the CMODE command in the client to set the
5615 founder auth data. Read the README to see how to set it.
5617 Added support to the CUMODE command to claim the founder
5618 rights. Read the README to see how to do it.
5620 Added support for the founder authentication to the Channel
5621 Entry in the server. Affected file silcd/idlist.h.
5623 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5624 server's CMODE command. Affected file silcd/command.c.
5626 * Added the following new functions into lib/silccore/silcauth.[ch]:
5627 silc_auth_get_method and silc_auth_get_data.
5629 * The server now saves the remote hosts public key to the
5630 SilcIDListData pointer. Affected file silcd/protocol.c.
5632 * The normal server now does not remove the channel entry from
5633 the cache if the founder authentication data is set. It used
5634 to remove it if the founder was the last one on the channel on
5635 the server and left the channel. The auth data is saved and
5636 if the channel is re-joined later the old entry is used with
5637 the old auth data. Affected files silcd/command_reply.c and
5640 * Removed the `pkcs' field from the SilcIDListData structure
5641 in the server; it is not used. Affected file silcd/idlist.h.
5643 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Fixed packet processing on slow links. Partial packets were
5646 never re-processed because the incoming data buffer was cleared
5647 by the application. Application must not directly clear the
5648 sock->inbuf, the packet processing routines handle it. Fixed
5649 this in client library and in server.
5651 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Fixed the WHOIS and IDENTIFY send reply function to really
5654 check whether to send list or just one entry. Affected file
5657 * Cleaned up the LEAVE command's channel key distribution. The
5658 affected file silcd/command.c.
5660 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5661 can enforce the channel mode as well. In that case the ID
5662 includes the ID of the server. The code now enforces the
5663 mode change if the router have different mode than the server.
5665 * The notify client operation with CMODE_CHANGE notify can now
5666 return NULL client_entry pointer if the CMODE was not changed
5667 by client. Application must check for this.
5669 * Added <Server ID> argument to INFO command to support server
5670 info fetching by Server ID.
5672 * Added silc_server_announce_get_channel_users to get assembled
5673 packets of channel users of the specified channel. Affected
5674 file silcd/server.[ch].
5676 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5677 was freed underneath the ID Cache.
5679 * Re-announce clients when the server received CHANNEL_CHANGE
5680 notify from the router. Affected file silcd/packet_send.c.
5682 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5685 crashed since it did not handle the fact that there is no cipher
5686 called "3" and didn't check the error condition. Now fixed.
5688 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5689 flag. It can be used to send message requests.
5691 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Implemented the RESTART command in the client.
5695 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5696 notice type messages. Added notice printing to the user
5699 * The channel keys are not re-generated if the channel's mode
5700 is PRIVKEY, ie private key on the channel exists. Affected
5701 files silcd/server.c and silcd/command.c.
5703 * Fixed a little bug in channel message delivery when channel
5704 private keys are set in the server. Affected file is
5705 silcd/packet_send.c.
5707 * Changed the setting on channel->on_channel = TRUE from the
5708 silc_client_save_channel_key to the JOIN command reply. The
5709 key payload is not received if the private channel key is set.
5710 Affected file lib/silcclient/command_reply.c and the
5711 lib/silcclient/client_channel.c.
5713 * When the CMODE_CHANGE notify is sent and the channel private
5714 key mode is removed the channel key must be re-generated in
5715 other cells as well. Added this support for the router in the
5716 silcd/packet_receive.c.
5718 * Added new local command NOTICE to send notice message on
5719 channel. Affected file silc/local_command.[ch].
5721 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Added new local command ME to the client. It is used to send
5724 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5725 some action. Affected file silc/local_command.[ch].
5727 * Changed channel_message and private_message client operations
5728 to deliver the message flags to the application. Added also
5729 the `flags' arguments to the silc_client_send_channel_message
5730 and silc_client_send_private_message functions. Affected file
5733 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Redefined the Private Message Payload to support private message
5736 keys and to support the new private message flags. Updated
5737 the protocol specs. Flags makes it possible to have for example
5738 CTCP style messages.
5740 * Added new type SilcPrivateMessagePayload and defined an API
5741 for it in the lib/silcclient/silcprivate.[ch].
5743 * Tested private message private keys successfully. Tested the
5744 private message key set, unset and list commands with the new
5747 * Redefined the Channel Message Payload to include the channel
5748 message flags (equal with private message flags) to support
5749 for example CTCP style messages.
5751 * Defined some of the message (for channel and private message)
5752 flags. Updated the protocol specs and added the flags to the
5753 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5755 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Added SilcKeyAgreementStatus type to the key agreement routines
5758 to indicate the current status and error if one occured.
5759 The status types are defined in the lib/silcclient/silcapi.h.
5761 * Added new local command KEY that is used to set and unset private
5762 keys for channels, set and unset private keys for private messages
5763 with remote clients and to send key agreement requests and
5764 negotiate the key agreement protocol with remote client. The
5765 key agreement is supported only to negotiate private message keys,
5766 it currently cannot be used to negotiate private keys for channels,
5767 as it is not convenient for that purpose.
5769 * Fixed a minor pending callback setting bug in the function
5770 silc_client_get_client_by_id_resolve, now the function works.
5771 Affected file lib/silcclient/idlist.c.
5773 * Added function silc_net_get_local_port to get local bound
5774 port by socket. Added to lib/silcutil/silcnet.[ch].
5776 * Added `sockets' and `sockets_count' fields to the SilcClient
5777 object. They hold the sockets of the listenning sockets in
5778 the client. Listenning sockets may be for example the key
5779 agreement server. Affected file lib/silcclient/client.[ch].
5780 Added functions the silc_client_add_socket and the
5781 silc_client_del_socket. They are exported to the application
5784 * Added ~./silc/clientkeys to support other client's public keys.
5786 * Renamed verify_server_key client operation to verify_public_key
5787 and added one argument to indicate the type of the connection
5788 (server, client etc.).
5790 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Added silc_server_connection_auth_request to handle the
5793 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5794 silcd/packet_receive.[ch].
5796 * Added silc_server_send_connection_auth_request into the
5797 silcd/packet_send.c to send the connection auth request packet.
5799 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5802 * Fixed the public key authentication in responder side in the
5803 server. The `auth_data' pointer includes the SilcPublicKey
5804 not the path to the public key. Affected file silcd/protocol.c.
5806 * Implemented the public key authentication in the initiator side
5807 in the server. Affected file silcd/protocol.c.
5809 * Removed the [RedirectClient] config section from the server
5810 configuration. Is not needed and I don't want to implement it.
5812 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Cleaned up the CMODE command in the server. It now works
5815 correctly and supports all the modes defined in the protocol.
5816 Affected file is silcd/command.c.
5818 * Added `hmac_name' field to the SilcChannelEntry in the server
5819 to hold the default HMAC of the channel. It can be set when
5820 creating the channel (with JOIN command). Affected files
5823 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5824 type to indicate the change of the current cipher and hmac
5825 on the channel. Client can safely ignore the <cipher> argument
5826 (if it chooses to do so) since the CHANNEL_KEY packet will
5827 force the channel key change anyway. The <hmac> argument is
5828 important since the client is responsible of setting the new
5829 HMAC and the hmac key into use.
5831 * Fixed the CMODE command in the client library as well.
5833 * Tested CMODE command in router environment successfully.
5835 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Show the version of the remote client (or server) when connecting
5838 to the server. It is logged to the log file. Affected file
5839 is silcd/protocol.c.
5841 * Fixed the KILLED notify handling in the client library. The
5842 client must be removed from all channels when receiving the
5845 Also, do not remove the client entry when giving the KILL
5846 command but when the KILLED notify is received.
5848 * Removed silc_idlist_find_client_by_nickname from the server.
5849 Not needed anymore. Affected files silcd/idlist.[ch].
5851 * Implemented the CHANNEL_CHANGE notify type handling to the
5852 server. Affected file silcd/server.c.
5856 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Added silc_server_send_notify_invite to send the INVITE
5859 notify between routers.
5861 * Implemented the INVITE command correctly to the server.
5863 * Implemented the INVITE notify type handling in the server.
5865 * Implemented the INVITE command to the client library and on the
5868 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Added function silc_server_get_client_resolve to find the
5871 client entry by ID from all ID lists and then resolve it
5872 (using WHOIS) if it cannot be found. Affected file is
5875 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Implemented the BAN command to the client library.
5879 * The JOIN command in the server now checks the invite list
5882 * Changed the silc_command_reply_payload_encode_va and the
5883 silc_command_payload_encode_va to support that if argument is
5884 NULL it ignores and checks the next argument. Affected file
5885 lib/silccore/silccommand.c.
5887 * Added silc_server_send_notify_ban to send the BAN notify
5888 type between routers.
5890 * Chaned the silc_notify_payload_encode to support that if
5891 argument is NULL it ignores and checks the next argument.
5892 Affected file lib/silccore/silcnotify.c.
5894 * Tested ban lists in router environment successfully.
5896 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Implemented BAN command to the server, in silcd/command.[ch].
5900 * Removed the BAN and INVITE_LIST modes from the CMODE command
5903 * Added function silc_string_match to regex match two strings.
5904 Affected files lib/silcutil/silcutil.[ch].
5906 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Redefined parts of the SilcChannelEntry in the server to support
5909 the new ban and invite lists.
5911 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Redefined the INVITE command. The same command can be used to
5914 invite individuals to the channel but also to manage the invite
5915 list of the channel (to add to and remove from the invite list).
5916 Updated the protocol specs.
5918 * Added new command SILC_COMMAND_BAN that can be used to manage
5919 the ban list of the channel. Updated the protocol specs.
5921 * Removed the channel modes: the SILC_CMODE_BAN and the
5922 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5923 in the CMODE command. The equivalent features are now available
5924 using INVITE and BAN commands. Updated the protocol specs.
5926 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5927 in the network about change in the current ban list. The notify
5928 type is not used by the client.
5930 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5931 support the invite lists.
5933 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Added new function silc_string_regexify that converts string
5936 including wildcard characters into regex string that can
5937 be used by the GNU regex library. Added into the file
5938 lib/silcutil/silcutil.[ch].
5940 Added silc_string_regex_combine to combine to regex strings
5941 into one so that they can be used as one regex string by
5942 the GNU regex library. Added into the file
5943 lib/silcutil/silcutil.[ch].
5945 Added silc_string_regex_match to match two strings. It returns
5946 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5948 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Imported GNU regex to the soruce tree into lib/contrib.
5951 Fixed some compiler warning from the regex.c.
5953 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Fixed MOTD command in the server to work in router environment.
5957 * Fixed the MOTD command in the client library to support
5958 the server argument in the command.
5960 * Added `nickname_len' argument to the silc_idlist_add_client
5961 in the server, as the `nickname' argument may be binary data
5964 * Added silc_idlist_get_channels to return all channels from
5967 * Implemented LIST command to the server. Affected file is
5970 * Implemented the LIST command to the client library and on the
5973 * Added [<user count>] argument to the LIST command reply.
5974 With private channels the user count is not shown.
5976 * Updated TODO and README.
5978 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * The client entry's data.registered must be TRUE even with
5981 global client entry on global client list. The data.registered
5982 is used to check whether the client is anymore in the network,
5983 for example with WHOWAS command so it must be valid.
5985 * Fixed the WHOWAS command in the server. It now actually works
5986 in router environment. Added function into silcd/command_reply.c
5987 silc_server_command_reply_whowas_save.
5989 * Added silc_idlist_purge function to the silcd/idlist.c
5990 to periodically purge the ID Cache.
5992 * Fixed INFO command in the server. It works now in router
5993 environment. Added <server name> argument to the INFO command
5994 reply. Updated the protocol specs.
5996 * Fixed minor bug in silc_idcache_purge to not purge if the
5997 expire value is zero.
5999 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6000 they were buggy because of the WHOWAS information.
6002 * Fixed local command MSG to handle the async resolving of
6003 the remote client properly. It used to fail the first MSG.
6004 Affected file silc/local_command.c.
6006 * Added `data_len' field to SilcIDCache context.
6008 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Update TODO. Todo in commands in the server.
6012 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6015 used by routers as broadcast packet to inform other routers
6016 about the changed user mode.
6018 Implemented the notify handling in the server. Affected file is
6019 silcd/packet_receive.c. Added the function
6020 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6022 * Added new generic Channel Payload and deprecated the New Channel
6023 Payload. The New Channel Payload is now the generic Channel
6026 * Added new argument `mode' to the silc_server_send_new_channel
6027 as it is required in the Channel Payload now.
6029 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6030 and created a new and real SilChannelPayload to represent the
6031 new generic Channel Payload. Implemented the encode/decode
6032 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6034 * Added silc_server_get_client_channel_list to return the list
6035 of channels the client has joined for WHOIS command reply.
6036 Affected file silcd/server.[ch].
6038 * Implemented the channel list sending in the WHOIS command reply
6039 in server and in the client.
6041 Implemented the channel list displaying on the user interface
6042 as well. Affected file silc/client_ops.c.
6044 * Added silc_channel_payload_parse_list to parse list of Channel
6045 Payloads. It returns SilcDList list of SilcChannelPayloads.
6046 Client for example can use this function to parse the list of
6047 channels it receives in the WHOIS command reply. The caller
6048 must free the list by calling silc_channel_payload_list_free.
6049 Affected files lib/silccore/silcchannel.[ch].
6051 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Added one new argument <user mode> to the WHOIS command reply
6054 to return the mode of the user in SILC. Updated the protocol
6057 Implemented it to the server and client.
6059 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Fixed the mode printing on the user interface on joining.
6062 Affected file silc/client_ops.c.
6064 * Implemented the UMODE command and user modes in general to the
6065 client library and to the user interface.
6067 * Implemented the UMODE command to the server.
6069 * The server now sends UNKNOWN_COMMAND error status if client sends
6070 unknown command. Affected file silcd/command.c.
6072 * All server commands now handle the command identifier the right
6073 way when sending the command reply to the client. The client can
6074 use to identify the command replies with the identifier.
6076 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Added silc_server_get_client_route to resolve the route to
6079 the client indicated by the client ID. Affected file is
6082 * Added silc_server_relay_packet as general function to relay
6083 packet to arbitrary destination. This deprecates functions
6084 like _send_private_message_key, _relay_notify etc. Affected
6085 file is silcd/packet_send.[ch].
6087 Removed silc_server_send_key_agreement,
6088 silc_server_send_private_message_key and
6089 silc_server_packet_relay_notify functions from the file
6090 silcd/packet_send.[ch].
6094 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6095 server. Affected file silcd/packet_receive.[ch].
6097 * Implemented the KILL command to the client. Implemented the
6098 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6099 Affected files lib/silcclient/command[_reply].c and
6100 lib/silcclient/client_notify.c. Implemented the KILL notify
6101 printing in the user inteface.
6103 * Fixed a lot silc_parse_nick memory leaks from the client
6104 library in the file lib/silcclient/command.c.
6106 * Changed the silc_server_send_notify_on_channels's `sender'
6107 argument from SilcSocketConnection to SilcClientEntry to
6108 check the sender as entry and not as connection object and not
6109 to send to the client provided as argument. The affected file
6110 is silcd/packet_send.[ch].
6112 * The notify packets that are destined directly to the client used
6113 to not to be processed by the server. Now changed that and the
6114 server processes all notify packets. After relaying the packet
6115 to the client the notify packet is processed in the server.
6117 * The silc_server_free_client_data now checks whether there is
6118 pending outgoing traffic for the client and purges the data to
6119 the network before removing the client entry.
6121 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6124 an client is killed from the SILC Network. Updated the protocol
6127 Added new function silc_server_send_notify_killed to the
6128 silcd/packet_send.[ch].
6130 * Added function silc_server_packet_relay_notify to relay notify
6131 packets that are destined directly to a client. In this case
6132 the server does not process the notify packets but merely relays
6133 it to the client. Affected file silcd/packet_send.[ch].
6135 Added also silc_server_packet_process_relay_notify to check
6136 whereto relay the notify. Affected file is
6137 silcd/packet_receive.[ch].
6139 * Implemented the KILL command to the server.
6143 * Added the backup schema desgined last fall to the protocol
6144 specs for everyone to see. The specification is in the
6145 *-spec-xx.txt draft and the packet type definitions for the
6146 backup routers is in *-pp-xx.txt draft. Thusly, added also
6147 new packet type SILC_PACKET_CELL_ROUTERS.
6149 * A big security problem in the implementation discovered. The
6150 signoff of an client did not cause new channel key generation
6151 which it of course should've done. The channel keys must be
6152 always re-generated when client leaves (or signoffs) the channel.
6153 The silc_server_remove_from_channels funtion now handles
6154 the channel key re-generation.
6156 * Added `sender' argument to the silc_server_send_notify_on_channels
6157 to not to send the client provided as argument. Affected file
6158 silcd/packet_send.[ch].
6160 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Implemented OPER and SILCOPER commands into the server and
6165 * Added silc_auth_verify and silc_auth_verify_data to verify
6166 the authentication directly from the authentication payload.
6167 It supports verifying both passphrase and public key based
6168 authentication. Affected file lib/silccore/silcauth.[ch].
6170 * Added `hash' field to the SilcIDListData structure. It is the
6171 hash negotiated in the SKE protocol. Affected file is
6174 * Slight redesigning of the SilcAuthPayload handling routines.
6175 Do not send SilcPKCS but SilcPublicKey as argument.
6177 * Implemented the public key authentication support to the
6178 serverconfig. The public key is loaded from the provided path
6179 and saved as authentication data to void * pointer. Thus,
6180 changed the unsigned char *auth_data to void *auth_data;
6182 * Fixed SHUTDOWN command to send the reply before the server
6183 is shutdown. :) Affected file silcd/command.c.
6185 * Fixed fatal bug in CONNECT command. The hostname was invalid
6186 memory and server crashed. Affected file silcd/command.c.
6188 * Fixed fatal bug in CLOSE command. The server_entry became
6189 invalid but was referenced later in the command. Affected file
6192 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Fixed fatal bug in failure packet handling. Server ignored
6195 the failure and thus crashed when it came.
6199 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6202 that the command may be executed only once in (about) 2 seconds.
6203 The old SILC_CF_LAG flag is same but allows command bursts up
6204 to five before limiting.
6206 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6207 server code. Various commands now includes the CF_LAG_STRICT
6208 flag to disallow any kind of miss-use of the command.
6210 * Fixed the silc_buffer_unformat to not to allocate any data
6211 if the length of the data is zero. It used to allocate the
6212 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6214 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * Changed the format of AdminConnection configuration section
6217 in the server. Added username of the admin to the format.
6218 Affected files silcd/serverconfig.[ch].
6220 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6221 to return admin configuration data by host, username and/or
6224 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Implemented WHOWAS command to the server. Added the functions:
6228 silc_server_command_whowas_parse,
6229 silc_server_command_whowas_send_reply,
6230 silc_server_command_whowas_from_client and
6231 silc_server_command_whowas_from_server
6233 * Added <Client ID> argument to the WHOWAS command reply. Updated
6234 the protocol specs accordingly.
6236 * Implemented WHOWAS command and command_reply to the client
6239 Implemented the WHOWAS printing on the user interface.
6241 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * Added new argument to the WHOWAS command reply, the real name.
6244 It is an optional argument. Updated the protocol specs.
6246 * Added SilcIDCacheDestructor callback that is registered when
6247 the SilcIDCache is allocated. The callback is called when
6248 an cache entry in the ID Cache expires, or is purged from the
6249 cache. Added into lib/silccore/idcache.[ch].
6251 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6252 to destruct the client entries when the cache entry expires.
6253 Other ID Cache's in server and in the client library ignores
6256 * If the ID Cache entry's `expire' field is zero then the entry
6257 never expires. Added boolean `expire' argument to the
6258 silc_idcache_add function in the lib/silccore/idcache.[ch].
6259 If it is TRUE the default expiry value is used.
6261 * Added silc_server_free_client_data_timeout that is registered
6262 when client disconnects. By default for 5 minutes we preserve
6263 the client entry for history - for WHOWAS command.
6265 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Added support to the server to enforce that commands are not
6268 executed more than once in 2 seconds. If server receives
6269 commands from client more frequently, timeout is registered
6270 to process the commands. Affected file silcd/command.c.
6271 Added new function silc_server_command_process_timeout.
6273 * Changed NICK_NOTIFY handling in client library to check that
6274 if the client's nickname was changed, so there is no need to
6275 resolve anything from the server.
6277 * Removed error printing from the WHOIS and IDENTIFY commands.
6278 If error occurs then it is ignored silently in the client library.
6279 The application, however, may map the received error to
6280 human readable error string. The application currently maps
6281 the NO_SUCH_NICKNAME error to string.
6283 * Made the command status message public to the application. Moved
6284 them from lib/silcclient/command_reply.c to
6285 lib/silcclient/command_reply.h. The application can map the
6286 received command status to the string with the
6287 silc_client_command_status_message function.
6289 * Added check to the server to check that client's ID is same
6290 as the Source ID in the packet the client sent. They must
6293 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6295 * Added dist-bzip hook to the Makefile.am to make bzip2
6296 compressed distributions.
6298 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Server now enforces the maximum length for the nickname and
6301 the channel as protocol specification dictates. 128 bytes for
6302 nickname and 256 bytes for channel name.
6304 * Moved the WHOIS printing to the application. The client libary
6305 does not print out the WHOIS information anymore, the application
6306 must do it. Renamed silc_client_command_reply_whois_print to
6307 the silc_client_command_reply_whois_save.
6309 The client's idle time is also sent to the application now, and
6310 the idle is shown on screen.
6312 * Added silc_client_command_reply_identify_save to save the
6313 received IDENTIFY entries.
6315 * Do not check for channel private keys in message sending and
6316 reception if the channel does not have the PRIVKEY mode set.
6317 Affected file lib/silclient/client_channel.c.
6319 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6322 just surfaced after chaning the JOIN procedure.
6324 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Added silc_client_get_clients_by_list to get client entries
6327 from Client ID list, that is returned for example by JOIN
6328 and USERS command replies. The application should use this
6329 function for example when JOIN command reply is received to
6330 resolve the clients already on the channel (library does not
6331 do that anymore as USERS command reply is not used in the JOIN
6332 procedure anymore). Affected files lib/silcclient/silcapi.h and
6333 lib/silcclient/idlist.c.
6335 * JOIN command reply and USERS command reply returns now SilcBuffer
6336 pointers instead of unsigned char pointers when returning
6337 the client list and mode list.
6339 * Added <Client ID> argument to the JOIN command reply, mainly
6340 for the server to identify for which client the command was
6341 originally sent. Updated protocol specs accordingly.
6343 * Added SilcDlist private_key pointer to the SilcChannelEntry
6344 in the client to support the channel private keys. Affected
6345 file is lib/silcclient/idlist.h.
6347 * Added SilcChannelPrivateKey argument to the function
6348 silc_client_send_channel_message so that application can choose
6349 to use specific private ke if it wants to. If it is not provided,
6350 the normal channel key is used, unless private keys are set.
6351 In this case the first (key that was added first) is used
6352 as the encryption key.
6354 * Implemented the support for channel private key handling.
6355 Implemented the following functions:
6357 silc_client_add_channel_private_key,
6358 silc_client_del_channel_private_keys,
6359 silc_client_del_channel_private_key,
6360 silc_client_list_channel_private_keys and
6361 silc_client_free_channel_private_keys
6363 Affected file lib/silcclient/client_channel.c.
6365 * Added the support for the private keys in the channel message
6366 sending and encryption and in the message reception and
6367 decryption. Affected funtions are
6368 silc_client_send_channel_message and silc_client_channel_message.
6370 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Added SKE's key verify callback to the client library's
6373 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6375 * Removed the statement that server (or router) must send USERS
6376 command reply when joining to the channel so that the client
6377 knows who are on the channel. Instead, the client list and
6378 client's mode list is now sent in the JOIN command reply to the
6379 client who joined channel. This is better solution.
6381 * Added function silc_server_get_users_on_channel and function
6382 silc_server_save_users_on_channel to the silcd/server.[ch].
6384 * Removed function silc_server_command_send_users from the
6387 * Do not show topic on the client library anymore. The topic is
6388 sent in the command reply notify to the application and the
6389 application must show the topic now.
6391 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6393 * Added client searching by nickname hash into the IDENTIFY and
6394 WHOIS commands in the server as they were clearly missing from
6395 them. Affected file is silcd/command.c.
6397 * Fixed a bug in private message receiving in the client library.
6398 The remote ID was freed and it wasn't supposed, now it is
6401 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Minor fix to the channel payload; allocate the data area, as it
6404 needs to be of specific length.
6406 * If the key agreement port is zero then the operating
6407 system will define the bound port. Affected files are
6408 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6410 * Added new function silc_channel_payload_decrypt into the file
6411 lib/silccore/silcchannel.[ch].
6413 * Moved the channel message etc, check from silc_packet_decrypt
6414 to applications. The library calls now a generic
6415 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6416 when the packet is either normal or special. This was done to
6417 allow more wide range of checking that was not allowed when
6418 the code was in library. Now applications can do virtually any
6419 checks to the packet and return to the library the decision how
6420 the packet should be processed. Affected files are
6421 lib/silccore/silcpacket.[ch].
6423 Added silc_server_packet_decrypt_check to the server and
6424 silc_client_packet_decrypt_check to the client library.
6426 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6427 to send with specified source and destination information.
6429 * Channel message delivery between routers was broken after the
6430 channel key distribution was fixed earlier. The channel key
6431 was used be to distributed to other routers as well which is not
6432 allowed by the protocol. Now this is fixed and channel keys
6433 really are cell specific and the channel message delivery between
6434 routers comply with the protocol specification.
6436 * Fixed various commands in server to check also the global list
6437 for the channel entry and not just the local list. The affected
6438 file silcd/command.c.
6440 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6442 * Added assert()s to buffer formatting and unformatting routines
6443 to assert (if --enable-debug) when error occurs. Affected
6444 file: lib/silcutil/silcbuffmt.c.
6446 * Changed to auto-reconnect to check whether the remote host is
6447 router and register the re-connect timeout if it is. It used
6448 to check that whether we are normal server, but router must do
6449 auto-reconnect with another router as well. Affected file
6452 * Removed the [<key len>] option from CMODE command as the cipher
6453 name decides the key length, nowadays. See the defined ciphers
6454 from the protocol specification.
6456 * Added [<hmac>] option to the CMODE command to define the HMAC
6457 for the channel. Added SILC_CMODE_HMAC channel mode.
6459 * Added [<hmac>] option for the JOIN command so that user can
6460 select which HMAC is used to compute the MACs of the channel
6463 * Added Hmac field to the Channel Message Payload. The integrity
6464 of plaintext channel messages are now protected by computing
6465 MAC of the message and attaching the MAC to the payload. The
6466 MAC is encrypted. Now, it is clear that this causes some
6467 overhead to the size of the packet but rationale for this is that
6468 now the receiver can verify whether the channel message decrypted
6469 correctly and also when private keys are set for the channel the
6470 receiver can decrypt the packet with several keys and check from
6471 the MAC which key decrypted the message correctly.
6473 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6474 lib/silccrypt/silccipher.[ch].
6476 * Added silc_hash_len to return the digest length into the
6477 lib/silcrypt/silchash.[ch].
6479 * Rewrote parts of Silc Channel Payload interface in the
6480 lib/silccore/silcchannel.[ch]. The encode function now also
6481 encrypts the packet and parse function decrypts it.
6483 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Fixed a minor formatting bug in the SKE's key material processing.
6486 It actually might have processed the keys wrong way resulting
6489 * Redefined the mandatory HMAC algorithms and added new algorithms.
6490 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6491 and hmac-md5 truncated to 96 bits. The mandatory is now
6492 hmac-sha1-96. Rest are optional (including the one that used
6493 to be mandatory). Rationale for this is that the truncated HMAC
6494 length is sufficient from security point of view and can actually
6495 make the attack against the HMAC harder. Also, the truncated
6496 HMAC causes less overhead to the packets. See the RFC2104 for
6499 * Added new [hmac] configuration section. The SKE used to use
6500 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6501 is of course wrong. The official names that must be proposed in
6502 the SKE are the ones defined in the protocol specification
6503 (hmac-sha1-96 for example). The user can configure any hmac
6504 using any hash function configured in the [hash] section. At
6505 least, the mandatory must be configured.
6507 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6509 * Added HMAC list to the SKE proposal list. It has now both
6510 hash algorithm list and HMAC list. This makes the protocol
6511 incompatible with previous versions. The SKE now seems to work
6512 the way it is supposed to work, for the first time actually.
6514 * Defined plain Hash algorithms to the protocol specification.
6517 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Implemented support for key agreement packets into the server.
6520 Added functions silc_server_key_agreement and
6521 silc_server_send_key_agreement. Other than these functions,
6522 server has nothing to do with this packet.
6524 * Added support for private message key packets into the server.
6525 Added functions silc_server_private_message_key and
6526 silc_server_send_private_message_key.
6530 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6531 called in the protocol's final callback instead in the END
6532 protocol state. This makes a little more sense and in the same
6533 time in client we can use the same protocol routines for normal
6534 key exchange and to key agreement packet handling as well.
6536 * Added to both client's and server's KE protocol context the
6537 SilcSKEKeyMaterial pointer to save the key material. We will
6538 bring the key material to the protocol's final callback by doing
6539 this. The final callback must free the key material.
6541 * Added SKE's packet_send callback into client's KE protocol
6542 context so that the caller can choose what packet sending function
6543 is used. This way we can use different packet sending when
6544 doing normal SKE when doing key agreement packet handling (in
6545 the key agreement packet handling we do not want to encrypt
6548 * Implemented the responder side of the key agreement routines
6549 in the client. The client can now bind to specified port and
6550 accept incoming key negotiation. The key material is passed
6551 to the application after the protocol is over.
6553 * Implemented the processing of incoming Key Agreement packet
6554 in the client. Added function silc_client_key_agreement to
6557 * Implemented the intiator side of the key agreement routines
6558 in the client. The client can now initiate key agreement with
6559 another remote client. The key material is passed to the
6560 application after the protocol is over.
6562 * Created client_keyagr.c to include all the key agreement
6565 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6566 SILC_TASK_CALLBACK except that it is not static.
6568 * Created client_notify.c and moved the Notify packet handling
6569 from the client.[ch] into that file.
6571 * Created client_prvmsg.c and moved all private message and
6572 private message key routines from the client.[ch] into that file.
6574 * Create client_channel.c and moved all channel message and
6575 channel private key routines from the client.[ch] into that file.
6577 * Changed silc_client_get_client_by_id_resolve to resolve with
6578 WHOIS command instead of IDENTIFY command, in the file
6579 lib/silclient/idlist.c.
6581 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Implemented the SKE's responder side to the Client library.
6585 * When FAILURE is received to the protocol do not trust it
6586 blindly. Register a timeout to wait whether the remote closes
6587 the connection as it should do it, only after that process the
6588 actual failure. This was changed to both client and server.
6590 * Added client_internal.h to include some of the structures
6591 there instead of client.h in lib/silcclient/.
6593 * Added function silc_task_unregister_by_callback to unregister
6594 timeouts by the callback function.
6596 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Some "Incomplete WHOIS info" errors has been appearing on the
6599 log files. Took away the entry->userinfo check from WHOIS
6600 reply sending. The entry->userinfo is now " " if client did not
6601 provide one. I thought this was fixed earlier but something
6602 is wrong still. Let's see if the error still appears.
6604 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Fixed a minor bug in the login when the channel key is
6607 re-generated in the server. It used to generate the key in
6608 wrong order and thus caused problems in the channel traffic.
6610 * Fixed a minor bug in channel key distsribution after
6611 KICK command. The key was not sent to the router even though
6614 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6616 * Added silc_ske_process_key_material_data as generic routine
6617 to process any key material as the SILC protocol dictates. The
6618 function is used by the actual SKE library but can be used by
6619 applications as well. This relates to the private message keys
6620 and the channel private keys since they must be processed the
6621 same way the normal SILC session keys. The protocol dictates
6622 this. Affected files: lib/silcske/silcske.[ch].
6624 Added also silc_ske_free_key_material to free the
6625 SilcSKEKeyMaterial structure.
6627 * Defined silc_cipher_set_key function to set the key for
6628 cipher without using the object's method function. The affected
6629 files: lib/silccrypt/silccipher.[ch].
6631 * Implemented silc silc_client_add_private_message_key,
6632 silc_client_add_private_message_key_ske,
6633 silc_client_del_private_message_key,
6634 silc_client_list_private_message_keys and
6635 silc_client_free_private_message_keys functions in the
6638 Added functions silc_client_send_private_message_key to send
6639 the Private Message Key payload and silc_client_private_message_key
6640 to handle incoming Private Message Key payload.
6642 * Added Cipher field to the Private Message Key payload to set
6643 the cipher to be used. If ignored, the default cipher defined
6644 in the SILC protocol (aes-256-cbc) is used.
6646 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Removed lib/silcclient/ops.h file.
6650 Redefined parts of the SILC Client Library API. Created new
6651 file silcapi.h that deprecates the ops.h file and defines the
6652 published Client Library API. Defined also private message key
6653 API and channel private key API into the file.
6655 This is the file that the application must include from the
6656 SILC Client Library. Other files need not be included by
6657 the application anymore.
6659 * Added new key_agreement client operation callback and also
6660 defined the Key Agreement library API for the application.
6662 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6665 is used by clients to request key negotiation between another
6666 client in the SILC network. If the negotiation is started it
6667 is performed using the SKE protocol. The result of the
6668 negotiation, the secret key material, can be used for example
6669 as private message key.
6671 Implemented the Key Agreement payload into the files
6672 lib/silccore/silauth.[ch].
6674 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Redefined ciphers for the SILC protocol. Added some new ciphers
6677 and defined the key lengths for the algorithms. Changed the
6678 code accordingly. The default key length is now 256 bits.
6680 * Fixed SKE key distribution function silc_ske_process_key_material
6681 when the key length is more than 128 bits. The default key
6682 length in SILC is now 256 bits.
6684 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6685 to indicate unsupported algorithm.
6687 * Renamed rijndael.c to aes.c and all functions as well.
6689 * Fixed a long standing channel key setting bug in client library.
6690 Weird that it has never surfaced before.
6692 * Fixed bug in channel deletion. If the entire channel is removed
6693 then it must also delete the references of the channel entry
6694 from the client's channel list as the client's channel entry and
6695 the channel's client entry share same memory.
6697 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6699 * Implemented CONNECT and SHUTDOWN commands in the client.
6701 * Implemented CLOSE command to the client.
6703 * Added the function silc_idlist_find_server_by_name into the
6704 files silcd/idlist.[ch].
6706 Added the function silc_idlist_find_server_by_conn into the
6707 files silcd/idlist.[ch].
6709 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * DIE command was renamed to SHUTDOWN. Updated the both code
6714 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6715 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6717 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6720 * Added function silc_server_create_connection function to create
6721 connection to remote router. My server implementation actually
6722 does not allow router to connect to normal server (it expects
6723 that normal server always initiates the connection to the router)
6724 so the CONNECT command is only good for connecting to another
6727 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6729 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6730 or some other client was kicked from the channel.
6732 Implemented the handling of the notify type to both client
6735 Implemented silc_server_send_notify_kicked to send the KICKED
6736 notify. It is used to send it to the server's primary router.
6738 * Implemented the KICK command into server and client.
6740 * Added `query' argument to the silc_idlist_get_client function
6741 to indicate whether to query the client from server or not if
6744 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6745 to indicate that the client is not channel founder.
6749 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6751 * Removed the rng context from SilcPacketContext structure and
6752 changed that the packet routine uses the Global RNG API.
6754 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added support for quit message that client can "leave" on the
6757 channel when it quits the SILC. It is ditributed inside the
6758 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6760 Added silc_server_free_client_data that will take the
6761 signoff message as argument.
6763 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6765 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6767 * Updated parts of the protocol specification to keep it up
6770 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6773 payloads in one packet.
6775 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6776 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6777 use now the new List flag.
6779 * Also deprecated the following packet types: REPLACE_ID,
6780 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6782 * Added list support for Notify packet in server.
6784 * Added silc_server_send_notify_channel_change to send the
6785 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6786 the silc_server_send_replace_id.
6788 * Added silc_server_send_notify_nick_change to send the
6789 NICK_CHANGE notify type. Deprecates the function
6790 silc_server_send_replace_id.
6792 * Added silc_server_send_notify_join to send the JOIN notify type.
6793 Deprecates the function silc_server_send_new_channel_user.
6795 * Added silc_server_send_notify_leave to send LEAVE notify type.
6796 Deprecates the function silc_server_send_remove_channel_user.
6798 * Added silc_server_send_notify_cmode and
6799 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6800 types. Deprecates the silc_server_send_set_mode function.
6802 * Added SERVER_SIGNOFF notify type to indicate that server has
6803 quit. This means that all clients on the channel from that
6804 server will drop. This can be also used when netsplit happens.
6806 Deprecated REMOVE_ID packet type since it is not needed anymore
6809 Added silc_server_send_notify_server_signoff to send the
6810 SERVER_SIGNOFF notify type. Deprecates the function
6811 silc_server_send_remove_id.
6813 Added also silc_server_send_notify_signoff to send the
6814 SIGNOFF notify type.
6816 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6817 SILC protocol from this day on. Changed the protocol
6818 specification as well.
6820 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6821 notify type. It is used between routers to notify about
6822 topic changes on a channel.
6824 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6827 * Partly updated the protocol specification to comply with the
6828 changes now made. It is still though a bit outdated.
6830 * The JOIN notify type now takes one extra argument <Channel ID>.
6831 The packet used to be destined to the channel but now the
6832 JOIN type may be sent as list thus it is impossible to
6833 destine it to any specific channel. By adding this argument
6834 it is again possible.
6836 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Added CREDITS file. The CHANGES and CREDITS file will appear
6839 in the distribution as well.
6841 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6844 types in the server's silcd/packet_receive.c.
6846 * Implemented CMODE and CUMODE to work in router environment.
6848 * Fixed minor encoding and decoding buglet from the
6849 lib/silccore/silcmode.c.
6851 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6854 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6856 * Changed all SilcConfigServer* and silc_config_server* to
6857 SilcServerConfig* and silc_server_config*, respectively.
6860 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Associated the ID (client or server ID) to the Authentication
6863 Payload to avoid any possibility of forging. Updated the
6864 protocol specification and the code accordingly.
6866 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6868 * The RSA key length is now save to the RsaKey context in the
6869 key generation process in lib/silccrypt/rsa.c. The key length
6870 is now used to figure out the maximum size of the block allowed
6871 to be encrypted/signed.
6873 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6874 is equivalent to the silc_mp_mp2bin but does not allocate any
6877 * Changed silc_mp_mp2bin API to take length argument. If it is
6878 non-zero then the buffer is allocated that large. If zero, then
6879 the size is approximated using silc_mp_sizeinbase, which however
6882 * Created Global RNG API which is global RNG that application can
6883 initialize. After initializing, any routine anywhere in the
6884 code (including library) can use RNG without allocating a new
6885 RNG object. This was done to allow this sort of use of the
6886 RNG in code that has no chance to allocate RNG object. All
6887 applications currently allocate this and many routines in the
6888 library use this. Affected file lib/silccrypt/silcrng.[ch].
6890 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6891 it to use the Global RNG API.
6893 * Defined Authentication Payload into protocol specification that
6894 is used during SILC session to authenticate entities. It is
6895 used for example by client to authenticate itself to the server
6896 to obtain server operator privileges.
6898 Implemented this payload into the lib/silccore/silcauth.[ch].
6899 Implemented also routines for public key based authentication
6900 as the new protocol specification dictates.
6902 Moved definitions of different authentication methods from
6903 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6905 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6906 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6907 silc_pkcs_verify_with_hash functions into the file
6908 lib/silccrypt/silcpkcs.[ch].
6910 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6912 * The client entry's userinfo pointer must be always valid.
6913 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6914 will fail since it requires the userinfo. Now, the userinfo
6915 is allocated as "" if actual userinfo does not exist. Actually,
6916 it must exist and it is totally Ok to drop client connections
6917 that does not announce the userinfo. However, we will make
6918 this workaround for now.
6920 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6921 to return the remote port by socket.
6923 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6926 SILC_SERVER_PENDING_EXEC and added an new macro
6927 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6928 data or when error occurs while processing the pending command.
6930 Added new argument `destructor' into silc_server_command_pending
6931 and to the SilcServerCommandPending object. This destructor is
6932 now called after calling the pending callback or if error occurs
6933 immediately. If error occurs the actual pending callback won't
6934 be called at all - only the destructor. The destructor may be
6935 NULL if destructor is not needed.
6937 All this applies for client library code as well. Similar
6938 changes were made there as well for the pending commands.
6940 In the client, the application must now allocate the
6941 SilcClientCommandContext with the silc_client_command_alloc
6944 * Added reference counter to the SilcServerCommandContext. Added
6945 function silc_server_command_alloc and silc_server_command_dup
6948 Same type of functions added to the client library for the same
6951 * Removed the cmd_ident from IDListData away since it is now
6952 global for all connections. It is the command identifier used
6953 in command sending and with pending commands. The affected file
6956 * Added reference counter to the SilcSocketConnection objecet to
6957 indicate the usage count of the object. The object won't be
6958 freed untill the reference counter hits zero. Currently only
6959 server uses this, and client ignores it. The client must be
6960 set to use this too later. The affected files are
6961 lib/silccore/silcsockconn.[ch]. Added also the function
6962 silc_socket_dup to increase the reference counter.
6964 This was mainly added because it is possible that the socket
6965 is removed underneath of pending command or other async
6966 operation. Now it won't be free'd and proper DISCONNECTING
6967 flags, etc. can be set to avoid sending data to connection that
6968 is not valid anymore.
6970 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6971 the connection. After that it sets SILC_SET_DISCONNECTED.
6972 It is, however, possible that the socket data is not still freed.
6973 The silc_server_packet_process now checks that data is not
6974 read or written to connection that is DISCONNECTED. The socket
6975 get's freed when the reference counter hits zero.
6977 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Changed the client operation API: channel_message operation's
6980 `sender' is now the client entry of the sender, not the nickname
6981 and the `channel' is the channel entry, not the channel name.
6983 In the private_message operation the `sender' is now also the
6984 client entry of the sender not the nickname.
6986 Affected file is lib/silcclient/ops.h and all applications
6987 using the client operations.
6989 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6991 * Moved the calling of ops->connect() from connect_to_server_final
6992 into receive_new_id functin since that is the point when the
6993 client is actually allowed to send traffic to network. The
6994 affected file is lib/silcclient/client.c.
6996 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6999 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7000 (if needs broadcasting) instead of broadcasting the packets one
7001 by one which would make a burst in the network traffic.
7003 * Added `broadcast' argument to the functions in silcd/server.[ch]
7004 silc_server_create_new_channel[_with_id] to indicate whether
7005 to send New Channel packet to primary router.
7007 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Added new function into the silcd/server.[ch] files:
7010 silc_server_create_new_channel_with_id to create new channel with
7011 already existing Channel ID.
7013 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7014 lib/silccore/silcpacket.h. This packet is used t send list of
7015 Set Mode payloads inside one packet. Server uses this to set
7016 the modes for the channels and clients on those channels, that it
7017 announced to the router when it connected to it. The protocol
7018 specification has been updated accordingly.
7020 * The silc_server_new_channel did not handle the packet coming
7021 from normal server as it normally does not send that. However,
7022 when it announces its channels it does send it. Implemented
7023 the support for that.
7025 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7026 into the file lib/silccore/id.h.
7028 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7030 * Fixed memory leaks in the functions silc_idlist_del_client,
7031 silc_idlist_del_channel and silc_idlist_del_server in the file
7032 silcd/idlist.c. All of those leaked like a sieve.
7034 * Fixed some small memory leaks in the client's function
7035 silc_client_notify_by_server.
7037 * Added functions into silcd/server.c: silc_server_announce_clients,
7038 silc_server_announce_channels and silc_server_announce_server.
7039 These functions are used by normal and router server to announce
7040 to its primary router about clients, channels and servers (when
7041 router) that we own. This is done after we've connected to the
7044 These functions effectively implements the following packet types:
7045 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7046 and SILC_PACKET_NEW_ID_LIST.
7048 * Added new functions into the silcd/packet_receive.[ch]:
7049 silc_server_new_id_list, silc_server_new_channel_list and
7050 silc_server_new_channel_user_list to handle the incoming
7051 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7053 * Added support of changing Channel ID in the function
7054 silc_server_replace_id. If the server that announces a channel
7055 to the router already exists in the router (with same name but
7056 with different Channel ID), router is responsible to send
7057 Replace ID packet to the server and force the server to change
7058 the Channel ID to the one router has.
7060 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7061 client that the Channel ID has been changed by the router. The
7062 normal server sends this to the client. Client must start using
7063 the new Channel ID as the channel's ID.
7065 Implemented handling of this new type into lib/silcclient/client.c
7066 into the function silc_client_notify_by_server.
7068 * Added new function silc_idlist_replace_channel_id into the files
7069 silcd/idlist.[ch] to replace the Channel ID.
7071 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7073 * Call silc_server_command_identify_check always when processing
7074 the IDENTIFY command in silcd/command.c
7076 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7079 send keepalive packets. The packet can be sent by clients,
7080 servers and routers.
7082 Added function silc_socket_set_heartbeat into the file
7083 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7084 If not set, the heartbeat is not performed. The actual
7085 heartbeat is implemented in the low level socket connection
7086 library. However, application is responsible of actually
7089 Added silc_server_send_heartbeat to send the actual heartbeat
7090 packet into silcd/packet_send.[ch]. Server now performs
7091 keepalive with all connections.
7093 * Added silc_task_get_first function into lib/silcutil/silctask.c
7094 to return the timeout task with shortest timeout. There was a bug
7095 in task unregistration that caused problems. TODO has been
7096 updated to include that task system must be rewritten.
7098 * The client library will now resolve the client information when
7099 receiving JOIN notify from server for client that we know but
7100 have incomplete information.
7102 * Rewrote parts of silc_server_remove_from_channels and
7103 silc_server_remove_from_one_channel as they did not remove the
7104 channel in some circumstances even though they should've.
7106 * Encryption problem encountered in server:
7108 The LEAVE command used to send the Channel Key packet to the
7109 router immediately after generating it. However, the code
7110 had earlier sent Remove Channel user packet but not immediately,
7111 ie. it was put to queue. The order of packets in the router
7112 was that Channel Key packet was first and Remove Channel User
7113 packet was second, even though they were encrypted in the
7114 reverse order. For this reason, MAC check failed. Now, this
7115 is fixed by not sending the Channel Key packet immediately but
7116 putting it to queue. However, this is more fundamental problem:
7117 packets that are in queue should actually not be encrypted
7118 because packets that are sent immediately gets encrypted
7119 actually with wrong IV (and thus MAC check fails). So, packets
7120 that are in queue should be encrypted when they are sent to
7121 the wire and not when they put to the queue.
7123 However, the problem is that the current system has not been
7124 designed to work that way. Instead, the packet is encrypted
7125 as soon as possible and left to the queue. The queue is then
7126 just purged into wire. There won't be any fixes for this
7127 any time soon. So, the current semantic for packet sending
7130 o If you send packet to remote host and do not force the send
7131 (the packet will be in queue) then all subsequent packets to the
7132 same remote host must also be put to the queue. Only after the
7133 queue has been purged is it safe again to force the packet
7136 o If you send all packets immediately then it safe to send
7137 any of subsequent packets through the queue, however, after
7138 the first packet is put to queue then any subsequent packets
7139 must also be put to the queue.
7141 Follow these rules and everything works fine.
7143 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7145 * Added new function silc_server_remove_clients_by_server to
7146 remove all client entries from ID list when the server connection
7147 is lost. In this case it is also important to invalidate all
7148 client entires as they hold the invalid server entry. This
7149 fixes fatal bug when server has lost connection and will reconnect
7152 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7154 * Made some sanity checks to silc_server_daemonise like to check
7155 whether the requested user and group actually exists.
7157 * Added sanity check to SKE's silc_ske_responder_finish to check
7158 that the public and private key actually is valid.
7160 * Invalidate the client's nickname when receiving Replace ID
7161 packet and the Client ID is being replaced. This means that the
7162 server will query the nickname if someone needs it (client)
7165 * Sort the ID Cache in client library when the ID Cache data
7166 has changed (needs sorting).
7168 * Do not allow for SILC client to create several connections to
7169 several servers. The client does not support windows right now
7170 and generating multiple connections causes weird behaviour.
7172 Irssi-silc client does support windows and can handle several
7173 connections without problems, see: www.irssi.org and SILC plugin.
7175 * Fixed some places where client was added to the IDList. The
7176 rule of thumb is following (in order to get everything right):
7177 If the client is directly connected local client then the
7178 `connection' argument must be set and `router' argument must be
7179 NULL to silc_idlist_add_client function. If the client is not
7180 directly connected client then the `router' argument must
7181 bet set and the `connection' argument must be NULL to the
7182 silc_idlist_add_client function.
7184 * The funtion silc_server_packet_send_local_channel actually did
7185 not check whether the client was locally connected or not. It
7186 does that now. Fixed a bug related to LEAVE command.
7188 * Fixed Remove Channel User payload parsing bug in server's
7189 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7191 * The server's silc_server_save_channel_key now checks also the
7192 global ID list for the channel as it might not be in the local
7193 list. Fixed a bug related to LEAVE command.
7195 * Is this the end of the [<unknown>] buglet that has been lurking
7196 around for a long time? A little for loop fix in server's
7197 silc_server_command_whois_parse that is used by both IDENTIFY
7198 and WHOIS command. At least, this was a clear bug and a cause
7199 of one type of [<unknown>] buglet.
7201 * WHOIS and IDENTIFY commands call the function
7202 silc_server_command_[whois/identify]_check function even if
7203 we are not router server.
7205 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Added --with-gmp configuration option. If set the GMP
7208 is always compiled in the SILC source tree. If not set then
7209 it is checked whether the system has the GMP3 installed. If
7210 it has then the GMP won't be compiled (the system's headers
7211 and library is used), if it doesn't have it then the GMP is
7212 compiled in the SILC source tree.
7214 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Changed RSA private exponent generation to what PKCS #1
7217 suggests. We try to find the smallest possible d by doing
7218 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7219 not security fix but optimization.
7221 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Added new config entry [Identity] to fork the server and run
7224 it as specific user and group. A patch from Bostik.
7226 * Imported Dotconf configuration library into lib/dotconf.
7227 This will be used to create the SILC configuration files later.
7228 It will appear in the distsribution after this commit.
7230 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7232 * A big code auditing weekend happening. Auditing code for
7233 obvious mistakes, bugs and errors. Also, removing any code
7236 Removed files for being obsolete:
7238 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7239 inline in the file lib/silcutil/silcbuffer.h)
7241 o lib/silcutil/silcbufutil.c (the header has inline versions)
7243 Changed code to fix possible error conditions:
7245 o The buffer formatting routines now check that the destination
7246 buffer really has enough space to add the data. This applies for
7247 both buffer formatting and unformatting
7248 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7249 unformatting was changed to accomodate following rules:
7250 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7251 sent to the function while XXX_*STRING will not allocate or copy
7252 the data into the buffer. Instead it sets the pointer from the
7253 buffer into the pointer sent as argument (XXX_*STRING used to
7254 require that the pointer must be allocated already). This change
7255 makes this whole thing a bit more consistent and more optimized
7256 (note that the data returned in the unformatting with XXX_*STRING
7257 must not be freed now). The routines return now -1 on error.
7259 o Tried to find all code that use buffer_format and buffer_unformat
7260 and added return value checking to prevent formatting and
7261 especially unformatting errors and possible subsequent fatal
7264 o Changed ske->x and ske->KEY to mallocated pointers in
7265 lib/silcske/silcske.h. Fixed possible data and memory leak.
7267 o Added return value checking to all *_parse* functions. Fixed
7268 many memory leaks as well.
7270 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7271 so that buffer overflows would not happen. All code now also
7272 checks the return value as it can fail.
7274 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7276 * Added reconnection support to server if the normal server looses
7277 its connection to the router (for example if router is rebooted).
7278 The server performs normal reconnection strategy implemented
7279 to the server. Affected file silcd/server.c.
7281 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7283 * Added new packet type SILC_PACKET_SET_MODE that is used to
7284 distribute the information about changed modes (for clients,
7285 channels and clients channel modes) to all routers in the
7286 network. Updated the protocol specification accordingly.
7288 Added functions into silcd/packet_send.c and
7289 silcd/packet_receive.c: silc_server_send_set_mode,
7290 silc_server_set_mode.
7292 Added new files silcmode.[ch] into lib/silccore that implements
7293 the encoding and decoding of Set Mode Payload. Added new type
7294 SilcSetModePayload. Moved the definitions of different modes
7295 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7297 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7299 * Oops, a little mistake in server's connection authentication
7300 protocol. The protocol is not ended with FAILURE but with
7301 SUCCESS if the authentication is Ok. :) Affected file is
7304 * Implemented NICK_CHANGE notify handling in server in the file
7305 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7306 the local clients on the channel. After the changing nickname
7307 in router environment snhould work and the [<unknown>] nickname
7308 should appear no more.
7310 The silc_server_replace_id function that receives the Replace ID
7311 payload now sends the NICK_CHANGE notify type also in the file
7312 silcd/packet_receive.c
7314 * Changed WHOIS and IDENTIFY command to support the maximum amount
7315 of arguments defined in protocol specs (3328 arguments). This
7316 fixed a bug that caused problems when there were more than three
7319 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7321 * Added extra parameter, command identifier, to the
7322 silc_client_send_command so that explicit command identifier
7325 Changed that ID list routines uses specific command identifier
7326 when sending WHOIS/IDENTIFY requests to the server so that they
7327 can be identified when the reply comes back.
7329 Affected files lib/silcclient/command.[ch],
7330 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7332 * Added `sender' argument to silc_server_packet_send_to_channel
7333 to indicaet the sender who originally sent the packet to us
7334 that we are now re-sending. Ignored if NULL. Affected file
7335 silcd/packet_send.[ch].
7337 * Added some server statistics support in silcd/server_internal.h
7338 SilcServerStatistics structure and around the server code. Also
7339 send some nice statistics information when client is connecting
7342 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7344 * Fixed channel ID decoding in server's JOIN command reply in
7345 silcd/command_reply.c
7347 * Fixed braodcasting of replace ID payload to not to send it if
7348 we are standalone server in silcd/packet_receive.c.
7350 * Fixed all channel message sending routines to not to send
7351 packets to clients that has router set, since they are routed
7352 separately in the same function earlier. Affects file
7353 silcd/packet_send.c and all channel packet sending functions.
7355 * In USERS reply, res_argv[i] are not allocated, the table
7356 is allocated. Thus changed that free the table, not its
7359 * In server's whois_check and identify_check if the client is
7360 locally connected do not send any WHOIS commands - they are not
7363 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7365 * Fixed some minor bugs in client when sending WHOIS command. The
7366 arguments was in wrong order.
7368 * Removed statis function add_to_channel from server in
7369 silcd/command.c that was previously used with the joining but
7372 * Tested USERS command in router environment successfully with two
7373 routers, two servers and two clients.
7375 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7377 * Reorganized the USERS command and command reply in client library
7378 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7379 When the command is given by user we register a pending command
7380 callback that will reprocess the command after the reply has been
7381 received from the server. When reprocessing the packet we then
7382 display the information. Thus, the USERS information is displayed
7383 now in the command callback instead of in the command reply
7384 callback. The processing of the command is same as previously
7385 when server has sent the command reply in the JOINing process.
7387 * Added to USERS command in silcd/command_reply.c to join the client,
7388 we didn't use to know about, to the channel after we've created
7389 a client entry for it. Also, for clienet we did know already still
7390 check whether it is on the channel or not and add it if not.
7392 * Removed silc_server_command_join_notify as the function and its
7395 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7397 * Changed the client's pending command handling to the same as the
7398 server's pending command handling. It is also now possible to
7399 execute command reply functions from other command reply
7400 function as the function callbacks for commands and command
7401 replies are one and same. The pending commands are not static
7402 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7403 in client connection context. Thus, pending commands are server
7404 connection specific as it is convenient.
7406 Changed the function silc_client_command_pending and
7407 silc_client_command_pending_del and added new function
7408 silc_client_command_pending_check. Removed the
7409 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7412 * Added cmd_ident, current command identifier, to the client
7413 connection context in lib/silcclient/client.h to keep track on
7414 command identifiers used in command sending. Client's command reply
7415 function handling now supports the mandatory command identifiers.
7417 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7418 funtions in client to fully support pending command callbacks.
7420 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7421 as one of the arguments to the application in the command reply
7424 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7425 before first releasing SILC but came back. Now it is removed again
7426 and should come back nomore. The FORWARDED flag was used only
7427 by the JOINing procedure by forwarding the command packet to router.
7428 Now, the JOINing procedure has been changed to more generic (due
7429 to various router environment issues) and FORWARDED is not needed
7430 anymore for anything. The protocol specification is yet to be
7433 Now, removed silc_server_packet_forward from server and the flag
7434 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7436 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7438 * Renamed NAMES command to USERS command. The NAMES was named that
7439 due to historical reasons. Now it is renamed. Also, rewrote
7440 parts of the USERS command. The nickname list is not sent anymore
7441 by the server. Only Client ID and mode lists are sent in the USERS
7442 command. Changed this also to the protocol specification.
7444 The client now resolves the names and stuff after it receives
7445 the USERS list from the server when joining to the channel.
7447 * WHOIS and IDENTIFY commands has been changed to support multiple
7448 Client ID's per command. One can now search for multiple users
7449 in the network by sending only one WHOIS or IDENTIFY command.
7450 Changed the code and the protocol specifications.
7452 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7453 uses silc_server_command_whois_parse to parse the request. */
7455 * If normal server, do not parse the WHOIS and IDENTIFY requests
7456 before sending it to the router. Saves some time.
7458 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * Fixed JOIN command on client library. Wrong number of arguments
7461 used to crash the client.
7463 * Added silc_server_channel_has_global function to check whether
7464 channel has global users or not.
7466 * Added silc_server_channel_has_local function to check whether channel
7467 has locally connected clients on the channel.
7469 * The silc_server_remove_from_one_channel now checks whether the
7470 channel has global users or not after given client was removed from
7471 the channel. It also checks whether the channel has local clients
7472 on the channel anymore. If it does not have then the channel entry
7473 is removed as it is not needed anymore.
7475 * The silc_server_notify now checks on JOIN notify whether the joining
7476 client is one of locally connected or global. If it is global then
7477 the channel has now global users on the channel and that is marked
7478 to the channel entry. Also, it now saves the global client to
7479 global list who is joining and JOINs it to the channel. This is
7480 for normal server, that is.
7482 Changed silc_server_send_notify_on_channel,
7483 silc_server_packet_relay_to_channel and
7484 silc_server_packet_send_to_channel check if we are normal server
7485 and client has router set (ie. global client) do not send the
7486 message to that client, as it is already routed to our router.
7488 * Implemented LEAVE notify type handling in silc_server_notify
7491 * Tested LEAVE command in router environment successfully. Tested
7492 with two routers, two servers and two clients.
7496 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7498 * Implemented SIGNOFF notify type handling in silc_server_notify
7501 * silc_server_remove_id now removes the client entry from all channels
7502 it has joined and thusly sends SIGNOFF notify type.
7504 * Rewrote the NAMES list generation in server by removing two excess
7505 loops. The lists are created now inside one loop.
7507 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7509 * silc_server_remove_channel_user checks now also global list
7510 for channel and client.
7512 * silc_server_new_channel_user checks now both local and global
7513 list for channel and client. Fixed a bug in client id decoding.
7514 Used to decode wrong buffer.
7516 * silc_server_channel_message checks now both local and global
7517 list for channel entry.
7519 * Tested channel joining (hence JOIN) in router environment
7520 successfully. Tested with two routers, two servers and two
7523 * Tested channel message sending in router environment successfully.
7525 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7527 * Added silc_server_save_channel_key into server.[ch] to save the
7528 received channel key in Channel Key payload processing. It is
7529 also used in JOIN command reply handling.
7531 Equivalent function silc_client_save_channel_key added into
7532 client.[ch] into client library.
7534 * Changed JOIN command reply to send information whether the channel
7535 was created or not (is existing already) and the channel key
7536 payload. Changed protocol specs accordingly.
7538 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7539 the request was sent by ID and not by nickname. Crashed on
7542 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7545 now correctly save the received data.
7547 * silc_server_free_sock_user_data now notifies routers in the
7548 network about entities leaving the network.
7550 At the same time implemented functions silc_server_remove_id
7551 and silc_server_send_remove_id to receive and send REMOVE_ID
7552 packets. The packet is used to notify routers in the network
7553 about leaving entities. The ID removed will become invalid in
7556 * Added function silc_idlist_del_server into server. Removes and
7557 free's server entry from ID list.
7559 * silc_server_private_message function now checks, if we are router,
7560 that the destination ID really is valid ID, naturally.
7562 * In router when NEW_ID packet is received (for new client) the
7563 hash of the Client ID is saved in the ID Cache but the
7564 client->nickname is set to NULL, instead of putting the hash
7567 IDENTIFY command now also checks that client->nickname must be
7568 valid. If it is not if will request the data from the server who
7569 owns the client. Added new function
7570 silc_server_command_identify_check.
7572 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7573 to set the command to already allocated Command Payload.
7575 * Tested private message sending in router environment with two
7576 routers, two servers and two clients. Fixed minor bugs and now
7579 * Fixed segfault from client's NAMES command. Used to crash if
7582 * Forwarded packets must not be routed even if it is not destined
7583 to the receiver. Changed server code comply with this.
7585 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7587 * Added `require_reverse_mapping' boolean value to ServerParams
7588 structure. If TRUE (not default) the server will require that
7589 the connecting host has fully qualified domain name.
7591 If the reverse mapping is not required and hostname could not be
7592 found the IP address is used as hostname.
7594 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7596 * Implemented version string checking to both client and server.
7597 The check is incomplete currently due to the abnormal version
7598 strings used in development version of SILC.
7600 * Changed all command functions in server to use the new
7603 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7605 * Changed char *data to unsigned char *data in ID Cache system to
7606 support binary data as ID Cache data. Changed code to support
7607 binary data in lib/silccore/idcache.c.
7609 * Renamed silc_server_packet_relay_command_reply to
7610 silc_server_command_reply as it is normal packet receiving
7611 function. Rewrote the function to accept command replys for
7612 servers and not only for clients.
7614 * Mark remote router always as registered server if we are connecting
7615 to it. Otherwise, commands sent by the router to us are ignored.
7617 * All ID List find routines now returns the ID Cache Entry pointer
7618 as well if requested.
7620 * WHOIS command works now in router environment, tested with two
7621 routers, two servers and two clients.
7623 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7624 in router environment (as it is almost equivalent to WHOIS) but
7625 hasn't been tested thoroughly. Added new functions:
7627 silc_server_command_identify_parse
7628 silc_server_command_identify_send_reply
7629 silc_server_command_identify_from_client
7630 silc_server_command_identify_from_server
7632 * Disabled route cache adding because adding two different ID's with
7633 same IP replaces the old cache entry thus giving wrong route.
7634 The entry->router->connection is always the fastest route anyway
7635 so route cache may not be needed. Of course, new routes maybe
7636 established after receiving the ID when the entry->router->connection
7637 might not be anymore the most optimal.
7639 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7641 * Add route cache for received ID for fast routing.
7643 * Added silc_server_packet_route to route received packet on router
7644 that is not destined to us.
7646 * Renamed silc_server_get_route to silc_server_route_get.
7648 * Added id_string and id_string_len fields into SilcServer to
7649 include encoded ServerID for fast comparing without excess
7650 encoding of the ID's.
7652 * Cleaned up WHOIS command on server side. Added following static
7655 silc_server_command_whois_parse
7656 silc_server_command_whois_check
7657 silc_server_command_whois_send_reply
7658 silc_server_command_whois_from_client
7659 silc_server_command_whois_from_server
7661 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7662 arguments in command replies. All command functions should be
7663 updated to use this macro.
7665 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * Minor typo fixes on command reply handling on server.
7669 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7671 * Added silc_server_command_add_to_channel internal routine to add
7672 the client to the channel after router has created the channel and
7673 sent command reply to the server.
7675 * Added generic silc_server_send_command to send any command from
7678 * Use static buffer with ID rendering instead of duplicating data.
7680 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7682 * Fixed a channel user mode bug when joining to a channel server gave
7683 everybody channel founder rights, oops.
7685 * We mark ourselves as the router of the incoming server connection
7686 if we are router ourselves. This way we can check in some packet
7687 sending functions whether it is locally connected server. For
7688 incoming router connections we put NULL.
7690 * For router sending packets locally means now always sending the
7691 packet cell wide; to local clients and local servers. For normal
7692 server sending packet locally means sending it to only local
7695 * Fixed the JOIN command to really work in router environment. If the
7696 channel is created it is always created by the router. Router is
7697 also responsible of making the initial joining to the channel,
7698 sending JOIN notify to the sending server and distributing
7699 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7700 does not exist server doesn't do anything else but forward the
7701 command to the router which performs everything.
7703 * Added silc_server_send_channel_key function to send the Channel Key
7706 * Added silc_server_create_channel_key to create new channel key. The
7707 channel key is now re-generated everytime someone joins or leaves
7708 a channel, as protocol dictates. Note: channel->key_len is the
7711 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7713 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7714 packet_receive.[ch] to separate packet sending and receiving
7715 routines. The server.[ch] now includes everything else including
7716 actual packet processing (writing and reading data) and other
7719 Renamed silc_server_private_message_send_internal to
7720 silc_server_send_private_message. The routine is still though
7721 used only to relay private messages as server does not send
7722 private messages itself.
7724 Renamed silc_server_new_channel to silc_server_create_new_channel
7725 and added new function sicl_server_new_channel that handles the
7726 incoming New Channel packet. Added also new sending function
7727 silc_server_send_new_channel to send New Channel Payload.
7729 * Added new function silc_server_notify to process incoming notify
7730 packet to the server/router. Server may then relay the notify
7731 to clients if needed.
7733 * Added new function silc_server_new_channel_user to process incoming
7734 New Channel User packet. Router will redistribute the packet and
7735 send JOIN notify to its local clients and locally connected servers
7736 if needed. Normal server will send JOIN notify to its local client
7737 on same channel when received this packet. Added also corresponding
7738 sending function silc_server_send_new_channel_user to sent the
7741 * Added boolean route argument to send_notif_to_channel and
7742 packet_send_to_channel functions to attempt to route the packet
7743 if it is TRUE and send only locally if it is FALSE.
7745 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7747 * silc_server_replace_id now broadcasts the received replace ID
7748 packet if it is not broadcast packet already. The router must
7749 broadcast to inform other routers about changed ID.
7751 * Added backpointer to server's router into SilcServer context in
7752 silcd/server_internal.h.
7754 * Fixed silc_server_packet_broadcast to send correct broadcast
7757 * The channel key is now distributed to the local client as soon
7758 as it is received from the router (in router environment) so that
7759 no other packet may be sent for the channel until client has
7762 * silc_server_remove_channel_user now broadcasts the received
7763 Remove Channel User packet if it is not broadcast packet already.
7764 The router must broadcast to inform other routers about removed
7767 * Added users field into SilcPacketContext that is a reference count
7768 of the context. One can increase the reference count by calling
7769 silc_packet_context_dup which is now changed to just increase the
7770 reference count instead of duplicating the data. The reference
7771 count is decresed by calling silc_packet_context_free that will
7772 free the data after the reference count hits zero.
7774 For now on the packet context and everything allocated into it
7775 (including the raw packet from network) must be freed by calling
7776 the new silc_packet_context_free function. Added also new function
7777 silc_packet_context_alloc that must be used now to allocate the
7778 context. This also means that if a routine is asynchronous from
7779 silc_[client/server]_packet_parse_type the packet context must
7780 be duplicated by calling silc_packet_context_dup. Otherwise it
7781 gets free'd after silc_[client/server]_packet_parse_type returns.
7782 Also, one must remember that if packet is duplicated then its
7783 reference count must be decresed by calling the free function as
7784 many times as it was duplicated.
7786 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7787 from both client and server.
7789 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7791 * Made joining to a channel working in router environment.
7793 * Cleaned up JOIN command on server side and create function
7794 silc_server_command_join_channel internal routine to make the
7797 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7799 * Changed silc_command_pending list to SilcDList. Also, added
7800 `ident' field to SilcServerCommandPending structure to identify
7801 the reply and to call correct callback.
7803 Added silc_server_command_pending_check function to replace the
7804 corresnponding macro. The silc_command_pending list is not
7807 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7808 to set identifier to previously allocated Command Payload. It
7809 is used to set identifier for command when resending Command
7812 * Added silc_command_payload_encode_payload to encode Command
7813 Payload buffer from SilcCommandPayload structure.
7815 * Added silc_argument_payload_encode_payload to encode Argument
7816 payload buffer from SilcArgumentPayload structure.
7818 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7820 * Changed WHOIS command to support router connection on server side.
7821 The whois request is always sent to router unless the server is
7822 standalone server. After server has received the reply from the
7823 router will it send the reply to the client.
7825 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7826 broadcast received broadcast packet. The function is used only
7827 by router. The broadcast packet is always sent to the router's
7830 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7831 render given ID to printable string, for log files for example.
7833 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * Made basic router to router connections working. At least they
7836 can now connect to each other but nothing really works the way
7837 they are supposed - yet.
7839 * Added new initiator token to RouterConnection configuration
7840 file in silcd/serverconfig.[ch]. It is used to tell whether we
7841 are the initiator to the remote router or whether we'll expect
7842 the other end to connect.
7844 * Moved registering of listener task to silc_server_init, hence
7845 the server starts listenning as soon as it is run, even if it
7846 does not have connections to other routers. Let's see how well
7849 * Changed default connection retry timeouts for more suitable in
7852 * Removed cipher and such arguments from silc_idlist_add_client
7853 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7854 Added new function silc_idlist_add_data to add the keys and stuff
7857 * Added SilcIDListData structure and added it to SilcClientEntry
7858 and SilcServerEntry as their first field in the structure. This
7859 way we can explicitly cast the ID entries to the SilcIDListData
7860 structure and get common data for the entries. In past, we had
7861 to first check what type of connection it is and then cast it to
7862 correct ID entry type. Now, we can directly cast the opaque
7863 pointer to the SilcIDListData (no matter what ID entry it actually
7864 is) and get the data needed.
7866 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7869 in some circumstances even if threre were timeout tasks, though not
7870 IO tasks, but tasks anyway. Now fixed.
7872 * Defined SilcServerConnection structure to hold connection specific
7873 stuff about directly connected servers and routers. The definition
7874 is currently in silcd/server_internal.h. I thought about having
7875 a bit more important role fro this struct but for now it is used
7876 only when connecting to other server (or router actually).
7878 * Added connecting retry support in server when connecting to
7879 router(s). The retry feature implement exponential backoff
7880 algorithm. Also, added SilcServerParams structure to hold default
7881 parameters for server. For now, it include these retry settings
7882 and are hard coded. After server is moded to be as Silc Server
7883 Library this structure will be more important.
7885 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7887 * Changed client librarys channel->clients table to SilcList and
7888 changed code accordingly.
7890 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7892 * Changed client's channel table to SilcList and changed code
7893 accordingly. Also changed SilcChannelClientEntry to include back-
7894 pointer to the channel so that client entry can use that structure
7895 as list as well and we have fast cross-reference to the channel.
7896 This change dramatically decreased the complexity of channel
7897 handling with client entry and vice versa (removed one extra
7898 loop when searching for channel entry from many functions).
7900 * Changed server->sim from table to SilcDList and changed code
7903 * NAMES command can now be used from user interface. It will show
7904 the user list on the channel, neatly.
7906 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7907 Code now saves realname of the user if it becomes available.
7909 * Renamed configure.in to configure.in.pre and made ./prepare
7910 script to automatically add correct version string to
7911 configure.in which it creates from configure.in.pre.
7913 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7915 * NAMES command reply now shows users mode with the nickname when
7918 * Moved silc_client_ch[u]mode[_char] functions from
7919 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7920 place sucks, they are utility functions and should be in some
7923 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7925 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7928 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7932 * Added TRQ (efficient deque and list library) into lib/trq. This is
7933 a very good list library that is currently used in the SILC. Defined
7934 SilcList API over the library because I didn't like the API very
7935 much. See lib/trq/silclist.h for the API and examples of how to
7936 use the API. Fixed various places in the code to use the new
7937 SilcList API. The SilcList is meant for lists that has a structure
7938 already defined as a list. It is not suitable to add just some
7939 context to the list (in TRQ, the context is the list actually).
7941 So, I defined SilcDList that can be used for the purpose where
7942 predefined list structure does not exit. This can be used as
7943 such list. Now some context just can be added to the SilcDList.
7944 Currently this list is not used in the SILC just yet, though there
7945 are a lot places where this can replace dynamically allocated
7946 tables and I will fix these places, later, to use SilcDList.
7947 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7948 and use TRQ internally).
7950 Also fixed some annoying warning messages that the original TRQ
7951 code generated. Also minor changes to TRQ's Makefile.in.
7953 * Added support for querying by Client ID to both WHOIS and
7954 IDENTIFY commands into server, as required by the protocol.
7956 * Removed method function pointers from SilcBuffer structure. They
7957 weren't used to anything and just increased the context size for
7958 no good reason. This change also made silc_buffer_alloc and
7959 silc_buffer_free functions inline functions.
7961 * Disabled command flooding detection support until it's fixed so
7962 that it accepts commands in but does not execute them more than once
7965 * Added silc_net_localhost(), to return local hostname, into
7966 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7967 that must be initialized before calling silc_client_init.
7969 * Added new function: silc_server_send_notify_on_channels to send
7970 notify messages to all channels client has joined. It is assured
7971 that the message is sent only once per client.
7973 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7974 lib/silcutil/silcutil.[ch] as silc_format function. The new
7975 function is generic and is used by server as well, not only by
7976 the logging routines.
7978 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7979 the provided version string was not acceptable. Added new function:
7980 silc_ske_check_version into lib/silcske/silcske.h. The function
7981 must be implemented by the application (client or server) and it
7982 does not reside in the SKE library. The function checks the version
7983 string remote end sent.
7985 * Added back pointers (to opaque context and to SilcSocketConnection)
7986 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7988 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7989 duplicate packet context structure.
7991 * Changed `notify' client operation to send same arguments as client
7992 receives from server except for ID's. ID's are mapped to correct
7993 ID entry and that is returned. Also, if channel entry is not sent
7994 by server but the notify is for channel the channel entry is sent
7995 to application (otherwise application doesn't know that it is for
7996 channel (library gets it from packet's Destination ID)).
7998 * Added silc_client_remove_from_channels into client library to
7999 remove a client from all channels it has joined to. Used when
8000 received SIGNOFF notify from server. Added also new function
8001 silc_client_replace_from_channels to replace old ID entry with
8002 new ID entry on all channels. Used when received NICK_CHANGE
8005 * Fixed ID Cache list handling in silc_idlist_get_client in
8006 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8007 to get (or query) client by ID.
8009 * Updated TODO list.
8011 * Added connection authentication status message defined by the
8012 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8013 support for these into the code in client and server side.
8015 * Added generic function silc_client_send_command to send any command
8016 with variable argument list. Application should use this function
8017 to send commands if the command functions provided by the library
8018 does not suite for the application's user interface needs.
8020 * Added new `failure' client operation. Application is notified about
8021 received failure packet if client is executing a protocol. In this
8022 case the protocol's execution has failed.
8024 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8025 is required by the protocol.
8027 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8028 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8031 * Added status flag to SilcSKE object to indicate realtime status
8032 of the SKE protocol.
8034 * Application receives now exactly same command reply arguments as
8035 the library receives from server. However, if ID is received the
8036 corresponding ID entry is returned to the application (eg. Client
8037 ID is mapped to correct SilcClientEntry entry and that is returned).
8038 Changed command_reply client operation due to this change.
8040 * Changed all ID's in commands and in command replys as ID Payloads.
8041 Change affected both client and server side codes.
8043 All ID's sent in SILC network (with execption of ID's in SILC
8044 Packet header) are sent in ID Payload to support variable length
8047 * Server now notifies nick changes and notifies all clients on
8048 the channels about the new nickname (about the new Client ID,
8051 * Implemented CMODE command to change channel modes. Supports all
8052 channel modes defined by the protocol specs except ban and invite
8053 lists. (Also, private channel key mode is supported but support for
8054 setting private channel key in client is missing, thus, this mode
8055 has no effect on client side (except that server requires that the
8056 client uses private channel key and normal channel traffic does not
8059 Also, invite mode works per se, but INVITE command does not work
8060 yet correctly, so you can set channel as invite only channel but
8061 inviting clients to the channel does not work (it is yet to be
8062 thought what's the best way to do it).
8064 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8065 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8066 Implemented CUMODE command to change user's mode on the channel.
8067 Supports all modes defined by the protocol specs.
8069 * Added NAMES command reply to return users modes on the channel.
8071 * Removed unnecessary and slow ciphers from lib/silccrypt.
8073 * Set SO_KEEPALIVE option to connection sockets by default.
8075 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8077 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8078 redefined the Notify Payload into protocol specs.
8080 * Added silc_id_payload_parse_id to get ID directly from raw
8083 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8085 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8086 accept searching by Client ID as well.
8088 * Added support for LEAVE and SIGNOFF notify types in client library.
8090 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8091 to parse ID Payload from raw data.
8093 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8095 * Added flags parameter into silc_ske_assemble_security_properties
8096 function in lib/silcske/silcske.[ch].
8098 * Changed notify client operation to fit better for notify messages
8099 sent by server. The notify payload received from server is now
8100 passed to the application (after parsing it to SilcNotifyPayload).
8101 It is application's responsibility to retrieve the arguments
8102 from the payload and show the message the way it wants. The message
8103 sent by server is implementation specific.
8105 * Changed public keys to comply with the protocol specification.
8106 Old public keys are not supported anymore and are not compatible.
8108 * Removed nickname from Channel Payload as the latest draft removed
8109 it. The client must resolve the nickname from the NAMES command
8110 reply received when it joined the channel.
8112 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8114 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8116 * Fixed some errors in protocol specification drafts.
8118 * Created lib/silccore/silcnotify.c to implement Notify Payload
8119 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8120 generic payloads described by protocol specifications. The file
8121 includes implementations for ID Payload and Argument Payload.
8123 * Changed Command Payload implementation to use the new Argument
8124 Payload. Changed command_xxxx_payload to command_payload_xxxx
8125 to comply with SILC coding conventions.
8127 * Added suppport for Argument Payload handling in Notify Payload
8128 implementation as protocol requires it. Added the new support
8129 into server and client lib as well.
8131 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Added support for multiple nicknames on same channel. [n] is
8134 added locally to the nickname if there are more than one same
8135 nicknames on the channel.
8137 * Server now sends all nicknames that matched WHOIS request.
8138 Client also shows the list received from server.
8140 * Added TOPIC command to client side. User can now set and show
8141 current topic on channel.
8143 * Added MOTD command to client and server. Also, server sends the
8144 motd when client connects to the server.
8146 * Changed version strings to comply ISO 8601.
8148 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8150 * Fixed protocol error handling in client library. It should now
8151 cope even if the SKE fails for some reason.
8153 * Made new protocol specification drafts for submitting to IETF.
8155 * Implemented TOPIC command to server in silcd/command.c.
8157 * Added two new notify types into lib/silccore/silcnotify.h:
8158 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8159 notify nickname change and topic setting/change on a channel.
8161 * API change of command_reply operation in client library. The
8162 application gets now the status type received from server as well.
8164 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8166 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8168 * Cras fixed and optimized the packet handling even further and
8169 it should work now. Minor change to the prototype of function
8170 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8172 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8174 * Added new function into lib/silcutil/silcschedule.[ch]:
8175 silc_schedule_with_fd to select() a specified fd. The function
8176 returns after timeout expires or data arrives or goes. The
8177 function is used by packet routines to wait that all data is
8178 received from network.
8180 * Fixed data reading from network in lib/silccore/silcpacket.c.
8181 The code now assures that all data is read from the fd and then
8182 continues packet processing. This was a bug fix since the code
8183 used to drop some data in some circumstances.
8185 * Added new function into lib/silcclient/client.[ch]:
8186 silc_client_start_key_exchange to start key exchange after
8187 connection has been established to server. The code internally
8188 now uses this funtion but its main purpose was to provide it
8189 for applications that perform their own connecting. After
8190 application has created a connection it merely calls this
8191 function to start the key exchange between client and server.
8192 The library takes care of everything else after that.
8194 Updated also lib/silcclient/README to explain the usage of
8197 * Do not send to application information that connection has
8198 been established. Application gets notified it by connect
8201 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8203 * Applied cras's patch to add silc_schedule_one function. The
8204 function runs scheduler once and returns.
8206 * Fixed the scheduler after cras messed it up. The timeout
8207 handling works now as it's supposed to work.
8209 * Added into lib/silccore/ silcnotify.h to include notify
8210 message types support. Changed silc_server_send_notify*
8211 functions, in server.[ch], to support those new notify types.
8212 Added the support for the notify types into client library,
8213 as well. Added new notify client operation into ops.h in
8216 * Changed silc_server_packet_send_to_channel to send normal
8217 packets instead of just channel message packets. The function
8218 is now used to send the notify packets to channels. It is not
8219 used to send channel message packets anymore, as server never
8222 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8223 va_arg()s as it seems to require it nowadays. I guess, if SILC
8224 is compiled with older va_arg() the new code should work anyway.
8226 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8228 * Splitted core library. Core library (lib/silccore) includes
8229 now only SILC protocol specific core (and common) components.
8230 Created new utility library (lib/silcutil) that includes more
8231 generic purpose stuff. The stuff for util library was taken
8232 from the old core library. This was minor and easy split.
8234 * Created SILC Client Library (lib/silcclient) that includes
8235 implementation of the SILC client without user interface. This
8236 was major move from silc/ directory. The code has been changed
8237 so that it is transparent towards the user interface. The
8238 silc/ directory includes now the same user interface as before
8239 and it uses the new client library. Read lib/silcclient/README.
8240 Basicly, the client library performs everything else related
8241 to SILC except user interface handling. Also, configuration
8242 files are considered to be part of user interface and library
8243 does not handle them.
8245 This change also changed a lot of structures, function naming etc.
8246 Most important change was that SilcClientWindow object was
8247 renamed to SilcClientConnection in the client library. Created
8248 also new file lib/silcclient/ops.h. Also added new files
8249 silc/local_command.[ch] and silc/client_ops.[ch].
8251 All these changes were made to make it easier for user interface
8252 designers to create what ever user interface for the SILC client
8255 It is also expected that the server will be moved to lib
8256 directory as well and SILC Server Library will be created;
8257 sometimes in the future.
8259 * Removed Local commands from lib/silccore/silccommand.h as
8260 they are application specific and new client library does not
8261 handle any of those anymore.
8263 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8264 old client implementation in silc/.
8266 * Added support for callback functions in SILC_LOG_* macros.
8267 Application can now set its own callbacks that will be called
8268 instead of using the default functions that will always print
8269 the debug messages to stderr (or stdout). Also, debugging can
8270 now be disabled by setting silc_debug to FALSE and re-enabled by
8271 setting it to TRUE. Note, that logging will still work even
8272 if debugging is disabled.
8274 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8275 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8276 silc_log_reset_debug_callbacks.
8278 * To enable debugging in silc client one must give now -d
8279 option on command line.
8281 * Changed silc_schedule_init to automatically allocate task queues
8282 if they are not allocated before calling it.
8284 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8286 * Added GMP 3.1 into math library.
8288 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8290 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8291 a channel in SILC network. The packet is used by servers and
8292 routers to notify other routers that user has left a channel.
8293 This little feature was missing until now. Added the feature
8294 to protocol specification as well.
8296 Added functions: silc_server_send_remove_channel_user and
8297 silc_server_remove_channel_user into server.[ch].
8299 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8300 lib/silccore/silcpacket.h. However, they are not implemented
8303 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8305 * Fixed joining to a channel and sending channel messages
8306 between server and router. The channel message sending should
8307 now work inside a cell.
8309 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Fixed the private message sending between server and router.
8312 The private message sending should now work inside a cell.
8314 * Added silc_server_replace_id into server.[ch] to replace
8315 existing ID in the SILC network.
8317 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8318 and silc_idlist_replace_server_id into idlist.[ch] in server.
8320 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8322 * Fixed the server to server connections. Server can again now
8323 connect to router. Router to router connections probably does
8326 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8328 * Added dynamic protocol registering support. Now protocols can
8329 registered and unregistered on the fly. Patch by cras.
8331 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8333 * Added lib/contrib directory to hold routines that some platforms
8334 don't have but are needed by SILC.
8336 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8337 into lin/contrib to provide getopt() and getopt_long() for
8338 those who don't have it.
8340 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8342 * Added AWAY command to client. When away message is set and
8343 client receives a private message packet the client automatically
8344 replies to the sender with the away message.
8346 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8347 bug seemed to be the cause of recent problems when compiling
8350 * Added version detection support to SKE protocol specification
8351 and added the new changes to the SKE implementation as well.
8352 There were other minor changes in the SKE protocol as well.
8354 Many changes in lib/silcske/silcske.[ch] and in
8355 lib/silcske/payload.[ch].
8357 * Added ^U functionality, clear input line. Patch from cras.
8359 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8361 * Mainly small bugfixes on core library. Fixed some debugging
8362 logging and buffer overflow in silclog.c.
8364 * Updated config.sub and config.guess on the distribution tree.
8366 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8368 * Added command lagging support in server. Client may execute
8369 commands now only once in two seconds.
8371 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8373 * Optimized packet reception. MAC computation and checking is now
8374 also more optimized. A lot previously duplicated code is now
8375 used as generic by both client and server.
8377 * Fixed key pair generation in clientutil.c
8379 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8381 * Added into lib/silccore/silcbufutil.[ch] new function;
8382 silc_buffer_realloc.
8384 * Moved generic packet sending/encryption functions to
8385 lib/silccore/silcpacket.[ch] from client and server. Some
8386 rewriting of the functions.
8388 * Moved all generic packet reception/decryption functions to
8389 lib/silccore/silcpacket.[ch] from client and server. The
8390 packet processing is now much cleaner in both client and server.
8391 These were major changes in both client and server.
8393 * Created many common functions in server to do packet sending.
8394 Previously code were duplicated a lot, this has been removed
8397 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8399 * Rewrote major parts of the ID cache system. Don't know
8400 whether it is better now or not but at least the API is more
8403 * Major rewrite on ID cache stuff on client because of the ID
8404 cache API changes. Added idlist.c to client.
8406 * Also major rewrite on ID cache stuff on server as well.
8407 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8408 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8409 in hand, instead they are all put into the ID cache system now.
8410 All server_idlist_* routines uses ID cache now instead of
8411 traversing its own lists (those lists does not exist anymore).
8412 SilcIDList though still exists. Also, SilcXXXEntry's are
8415 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8417 * Finally made the SKE implementation compliant to the protocol
8418 specification. All mp integers are now binary encoded as
8419 opposed being HEX encoded.
8421 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8424 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8425 functions: silc_[encode/decode]_pem. Also added function
8426 silc_encode_pem_file to PEM encode with newlines ('\n') for
8429 * SILC public keys are now encoded either PEM or binary. Same
8430 option is for private keys as well. By default private keys
8431 are binary encoded and public keys PEM encoded. Silly HEX
8432 encoding were removed.
8434 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8435 function to create fingerprints.
8437 * Fixed a bug in SHA1; does not change the original data anymore.
8439 * Partly implemented INFO command on client and server side.
8440 Fixed CLEAR command. Changes to SERVER command; show current
8441 server(s) when giving command without arguments. Added
8442 VERSION command to client.
8444 * Added check to server that unregistered connections cannot
8445 execute commands (unless it is specificly allowed).
8447 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8449 * Fixed screen refresh.
8451 * Fixed channel joining bug from client. On some circumstances
8452 client tried to join to a channel it had already joined.
8454 * Added public key verification process into client's protocol.c.
8455 The client now verifies the public key from user and saves
8456 it into ~./silc/serverkeys/ directory.
8458 Added into: clientutil.[ch]: silc_client_verify_server_key.
8460 * Changed SKE protocol's silc_ske_initiator_finish function
8461 to accept callback function that verifies the received public
8462 key. Removed old silc_ske_verify_public_key function.
8464 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8466 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8467 silc_pkcs_private_key[_data]_set.
8469 * Made the password and public authentication more cleaner in
8470 server's protocol.c.
8472 * Removed historic and obsolete protocol `channel_auth' from
8473 both client and server.
8475 * Removed wrong way of sending command status messages from
8476 server to client in server's command.c. The old way violated
8477 protocol specification.
8479 Changes to silccore/silccommand.[ch]: removed
8480 silc_command_encode_status_payload -> not needed anymore,
8481 changed silc_command_encode_payload_va to accept extra
8482 argument on variable argument list. The argument type must
8483 now be provided to the function. Also, added new function:
8484 silc_command_encode_reply_payload_va which is same as
8485 normal command_encode_payload_va except command status type
8486 is provided as extra argument.
8488 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8490 * Added ~./silc directory handling. The directory includes the
8491 public and private keys for the client.
8493 Added silc_client_check_silc_dir, silc_client_create_identifier
8494 and silc_client_load_keys.
8496 * Implemented SILC protocol compliant public key. Added public
8497 and private key saving to and loading from files.
8499 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
